  1. I parked on an incline today and spotted water flowing away from underneath my 1997 Mazda 626LX 4cly 2L. Got home and had a peak with flashlight. Small amount of water, maybe 1/2 cup, after a climb into the hills. The water is dripping from a small rubber hose that sticks out about an inch from the left back wall of the engine compartment. I suppose that's the function of that little hose but it doesn't seem natural that it's doing that. Most cars don't have little puddles of water forming under the car after running a few minutes. What's up with this? This car doesn't get a whole lot of use, only around 1000mi/year. It has under 33,000 miles on it. Probably unrelated but I took the same ~10 mile round trip a few days ago (including 800 foot climb into the hills) and something seemed wrong. It seemed to act like the idle was set too low, like it was about to stall out, but it didn't. Whatever that was seems to have stopped happening, it was just that one day.
  2. Why does this happen? I only drive the car on average ~1500 miles/year. Most of the time the car sits in my driveway with the windows rolled up. The interior surfaces of the windows get a white filmy coating. I notice it most when I drive, I like a clean windshield. But cleaning the outside does not give me that if the inside has that film. I have to clean the interior surfaces to get that true transparency. What's up with that? I'm in Berkeley, CA. The air pollution around here is pretty moderate most of the time, I'm near the coast, breezes are typically off shore. Is there stuff inside the car that's off-gassing? The seats are leather. If I were to clean all the windows' interior, I am pretty sure in a month there would again be an obvious film. I figure that other people are seeing this and have some ideas. What do you think?
  3. The problem's fixed. As hypothesized in the quote, water was penetrating the weatherstripping by working its way into the crease and up and over the ~1/2" flange and out the other (interior) side. I removed the weatherstripping, gouged out a lot of the gunk in the crease, let the fully soaked crease dry out. I cleaned most all of the dried sealant that was on the exterior of the weatherstripping with Goo Gone (took a couple hours). Then I used Permatex to reseat the weatherstripping and for good measure I applied black GE Silicone II all around the weatherstripping's exterior where it contacts the metal to further insure no water will get through. It's rained around 2.5" the last couple of days and I took the car for a drive in the rain, too, and the interior of the trunk is bone dry. Now have to reassemble the trunk interior including making a new support for the right rear that goes under the carpet-mat. The other one had completely disintegrated from the water intrusion.
  4. I used silicone to seal 8 or so points where it looked like a little water was entering, it's been a few days and today I washed the car. There was a little water coming down where the left-most arrow is pointing. I think the water is getting in through the seal. I don't believe it's getting between the seal and the trunk lid. What I think is happening is that the water's getting over the ~1/2" steel flange that the seal fixes on. The rubber seal pulls right off the flange, all around, and I see a lot of water all in the seal groove. Thus, water's passing over the flange. I see a black adhering substance, it's like a black putty, that's soft. There's also dirt on the flange and in the seal groove. Once water gets over the flange I don't know how it's getting into the trunk, it's baffling, but I'm thinking that if I can stop water from getting through the seal groove/flange it will stop getting into the trunk. I'm thinking I either have to buy and install a new seal or reseat the old seal with seal adhesive. The seal looks good, as far as I can tell, but I could be wrong. Anyway, getting the inside of the seal's groove clean and dry looks like not an easy thing to so. I was going to try using silicone but Youtube videos show people using squeeze tube adhesive, e.g. by a company called Steele. Anyone have a take on this?
  5. OK, I just called the toll free number on the 2.8oz tube of GE Silicone II (White) that I used (figure to use the leftover in my bath and kitchen). The guy said that their Silicone II sealant is not acid, so there won't be a corrosion issue. I asked him about their Silicone I and he said that one IS acid! So, I bought the right one! I spent some time deciding, get a 10+ ounce tube, get Silcone I or II??? Luckily, I didn't get the wrong one.
  6. Don't ever use silicon, it's even worse than your leaking problem. silicon containes vinigar, wich is acid as you probably know. You will create major rust problems if you use 100% silicon. Use acrilic or polyurethane based sealant. Yipes! I just used GE Silicone II White on all points. Is this true? This will cause rust? aleekat said use Silicone, noone else said I shouldn't Should I be concerned? I can remove it and us something else. I have a can of Rust-O-Leum LeakSeal, thought it was clear, but when I went to use it a couple days ago on the antenna leak I found out it is Aluminum! Doh! Anyway, it won't be visible when I put the carpet-matting back in. I am hesitant to put that in yet before a real good rain comes. Hopefully that will be in a week, but the forecast has a definite maybe bias.
  7. It rained a little a 5, Friday. By a little I mean maybe ~0.04 inches! Barely enough, but the streets did puddle a little and I drove in it. I can see around 4-5 places where there's a trickle of water shown by the talc. To me, they appear minor but it is hard to tell. I am about to run clear silicone on a few spots. One trail is under where the antenna goes. I see no way I can apply from inside, so I'll put a small bead around the top where the antenna mast penetrates. Other spots: There's one from a fitting on the left side that comes from the tail light assembly. It doesn't seat flat, I'll put a bead there inside. 2 or 3 other fittings have small trails as well. I'll just bead-up what I can and hope that does it. It think there may be something else doing on. I don't see what you guys are talking about in terms of "sheet metal seams." Can someone take a picture and post? Here's a shot that shows a couple of the trails. There's one under the antenna to the left, around 3 to the right above the depression behind the wheel. But I don't see how all that water could have accumulated under the spare except from the two trails you see in this shot.:
  8. I gave the car a much tougher squirting with nozzeled hose all over, today (a full 8 minutes), still not a drop penetrating the trunk, far as I can tell, and I looked pretty close. Another theory -- I live 1.5 miles from a major earthquake fault, said to be the most dangerous in the USA in terms of potential catastrophic results. As well, my house is 106 years old and could be destroyed at any time. So, I keep provisions in the car and the garage (would could also collapse). I figure the car should weather a quake out there. I have some food, shoes, clothes, etc. in the trunk, keep a gallon of water in front of the right back seat. I may have had water in the trunk that escaped its container. I don't remember doing that or finding a container that broke, but that could have happened. I really can't account for the water in the trunk. I'll wait out the weather due this week before putting anything back in the trunk including the carpet-matting.
  9. I can wait but I am antsy to find an answer. The current 10 day forecast for 94703 is Wednesday, Thursday, Friday have respectively 60% PM, 60% AM, 50% PM chance of showers. So, significant rainfall (enough to reveal my problem) is no guarantee. I could hit the car with nozzeled hose again, this time more adamantly, for longer and see if any water comes in. I couldn't see a drop yesterday after a 3-5 minutes basic hosing dirt off the car with pressured blasting of the car, what I typically do as a car wash. I don't remember ever soaping my car, I just blast with nozzle, and sometimes I use car wash mitts and reblast, to get the car looking nice. I'm still wondering if water in a slightly open window could get in the trunk and if water kicking up from the road in rainy conditions could have accounted for the ~40+ ounces of water that was under the spare a few days ago. It's a real head scratcher for me. I'm about to put the removed trunk matting out in the sun, I had it in the garage overnight (there's no room for the car in the garage, the car remains in the weather on my driveway, as always). The matting is almost dry, a few more hours out in the sun should have it very dry. I will leave it in the garage, though, until I can hopefully identify and fix whatever's letting water into the trunk.
  10. Should I take it to mechanical car wash or just wait for Wednesday? They expect light rain in the PM, 60% chance.
  11. I don't have a sunroof. Are there holes for one anyway?
  12. OK, I have something to report. I can't find a leak. Water poured in the gutters, all around results in not a drop inside. I then gave a ~1/2 minute hosing to the trunk area, went inside (where I'd lowered the back seats so I could see the inside of the trunk from inside the car using a flashlight), and didn't see a drop of water. I then dusted the entire inside of the trunk pretty heavily with talc and put a nozzle on the hose and gave the entire car my typical quick-wash for 3-5 minutes, which blasts off 95% of the dirt/dust, went back inside the car and don't see any indication that any water has penetrated inside. Hmm. My conclusion is this: I may very well have left a window not entirely closed and rain water (or even hose water), may have gotten in and filled the trunk somehow, enough where I found ~1.5 quarts of water under the spare tire the other day. I don't know what else to think. It's supposed to rain on Thursday, so I'll just leave everything out of the trunk until after that rain storm and see if I see water in there. I remember seeing a window slightly open in the past during rainy weather, maybe last winter, maybe even this winter. My windows aren't so hot. In fact the left rear window often as not I have to grab and pull on it to get it to go up, with the switch on. The right windows are very slow to go up, the driver's window is pretty OK, at least compared to the others. This may have contributed to the windows not being entirely closed and allowing water to get in. Why that water would accumulate in the trunk, I don't know, but I guess it could. Seems unlikely, though. Here's another theory: Is it possible that water penetrated to the inside from underneath the car when driving in the rain, kicked up by the tires rolling over wet surfaces and across puddles? I really don't know what to think. Maybe I should take the car to a mechanical car wash, ya think?
  13. I'm trying to picture this. Use the drinking glass with the trunk open? You mean pour water in the gutters on the OUTSIDE of the rubber from above at both sides and see if water somehow makes its way into the interior from the gutters? I got the mat out, it's big, around 7' x 4'. It was wetter than I thought, in the fiberglass ~1" thick under-padding. It's in the sun now, should be dry by afternoon (it's 11:20AM now).
  14. Thank you! I'm going to try and get all over this today. I have next to me an unopened caulking gun tube of Ace clear 100% silicone that I bought who knows how many years ago. The sticker on the tube says $4.29 so you can guess how long that tube's been sitting in my workroom! I suppose it's still good, there's flex in the tube, will see how it comes out. How do you spread the powder? I figure to try using a 2-3" cheapie brush. It's 7:40AM right now, I figure to get going on this in 2-3 hours, after it warms up and the morning dew has pretty much dried out, then open everything up in the car, windows, hood, trunk and have at it.
  15. Thanks, Ray. Appreciated. Now, I think the moisture is under control (it's almost dry now, after tomorrow I think it will be dry, with more time with the lid up and a fan inside). BUT it's supposed to rain on Thursday, 5 days away. So, I have a few days to try to stop the leak(s). I found a tarp in a closet that I could throw over the car Thursday. I saw a thread in these forums searching yesterday by a guy who found around 10 different leaks in the trunks of his Mazdas (he had several Mazdas), so I figure there's a real possibility that there's more than one leak in this car. I'm kind of thinking that the leak(s) is near the very rear of the trunk. I see evidence, but it could be deceptive. There's (maybe telltale) dirt in the channels back there, but that might not be where the water's GETTING IN. There is a hint of mold on the bottom of the easily removable mat that covers the spare tire. The bottom of that mat is compressed wood, so it would be suseptible to mold. I let that dry out a couple days ago in the sun. I don't smell anything in the car, I'm almost surprised by that. I guess they don't have a lot of stuff in that car that's biodegradable, is my thought. Yeah, I see a lot of posts about getting in the car. Now I just got your thing about "let you out." You mean being locked in the trunk, like that scene in Jackie Brown (great movie). Well, my 626 allows putting the back seat down so you can access the trunk from the passenger compartment. I have used that feature a time or two doing lumber runs to Home Depot. I don't have a buddy (yeah, I'm weird that way), I could ask the chick next door, we are friendly. I mean a hose (I have never taken a car to a carwash!). Or, I could have a sprinkler attachment on my hose that has a spike to hold it in the ground. I think I could even just blast the rear of the car with a hose all around and then go in the trunk and probably see where water is penetrating. It's almost totally dry in there now, there's nothing but the carpet-mat padding (and the ~1" thick probably fiberglass attached pads beneath it at the right and left rear, underneath, one of which was very wet a couple of days ago), it's all of one piece, basically, probably around 10 square feet. I'll see if I can remove that tomorrow. Of course, I'll have an eye on being able to replace it reasonably easily before I forcefully rip it out! Absent that, I think I have it pulled away enough where I have a good chance of seeing where water's getting in. I don't think it's important to remove the carpet-mat and attached fiberglass padding at this point except to help identify where the water is getting in. I think it's pretty much dry, or will be shortly. But I may need to remove that stuff to see where the water's penetrating.
