The Monte has been parked more than driven over the past year. I took it out yesterday and found that there was a puddle of water sloshing around the passenger side rear floor. Front passenger carpet was wet also.

Pulled out the wet vac and got as much up as possible but the under-padding is still soaked and the interior smells of milder in general.

First I thought it was from T Tops but its dry up there. Read some posts and maybe its the heater core or other seams up in the front.

Any ideas/suggestions on what to do next? I guess its time to replace the carpet but obviously I need to identify and repair the leak first.
Thanks.

Front looks like to much beer and bad kidneys. laugh

If it was the heater core you would smell antifreeze and the water level should be low. Easy test is to bypass the heater core. But, I would tend to rule out the heater core if it sat more than being driven unless the core has a big leak to allow it to drain.

With that amount of water in the back seat well I would suspect the T-Tops. Looks just like my 82 Vette. Check that with a water hose.

Pull the carpet and underpadding out of the car. Leave the car out in a hard rain and see where the water is leaking in from. Hose water usually does not leak in as easily as rain does. You also will want to look at this thread. http://www.montecarloss.com/community/ubbthreads.php?ubb=showflat&Number=864472&page=1 Sadly finding and fixing body leaks can be a very long and involved job. Also use the good stuff epoxy seam sealer, not the crappy 1 part seam sealer chain auto stores sell.

Thanks for the replies. I ordered the new interior carpet from Mikes Montes today in anticipation of fixing the leak. I'll rip out the old smelly carpet this weekend and start the process of trying to repair the leaking area. I'll check out that drain in the ac area. It could very well be the culprit as I park under trees.

I can see this project turning into something bigger and more expensive than I want tackle at this time.

OEMTECH... that "beer and bad kidney" remark cracked me up! When I pulled up the front passenger side mat and found those stains I was pretty much grossed out myself!

While you have the seats and console out I would clean the floor, reseal, paint POR?and add some Dyna Mat. But, make sure you have the leaks fixed or you get to do it all over again.

I'd also guess t-top related. My hardtop SS did leak enough that after a bad storm one time water pooled up in the back passenger floor though. Could be door weatherstripping as well as the windshield area or heater core. Lots of variables and potential leak spots. The water might of dried up around the t-top area before you checked it too...just a thought.

I'm sure all the weatherstripping is questionable and its high on the to do list.

So I look under the hood earlier and noticed a big opening into the heater core area. I had a local shop replace the heater core a number of years ago and always found it strange that there was sort of a sponge over in that hole blocking it up. Now whatever that was is missing. This has got to be part of the problem.

I'm going to follow these directions Heater Core Replacement and pull out the blower motor and see if that vent is clogged up.

The sponge that was around the heater core inlet and outlet were fine, it keeps bugs and stuff from going in the box through the heater core inlet and outlet. Is not the heater core, thats way to much water, even if it could leak, you would see/smell it while your driving it, and even that, the car would start to over heat because of how much coolant/water is lost. Its either

A.) A seal fro mthe T-tops
B.) The AC/heater box drain is clogged
C.) The passenger side A pillar seal that is bad
D.) A kid on your block using a teleportaion device to teleport water inside your car.
E.) Umm, forgot...

Theres been alot of people thinking that the T-top seals are great, just because there tight on mst of the rubber, but that doesnt mean that it wont leak, all is needs is one place that is open, then it will do the works, the longer it leaks, the more rust you could have, or, if you havent checked already, you might have rust under the T-top seals, so instead of the seals being bad, it leaks through the rust spots.

Yeah... the heater core itself is not leaking. That's just plain water inside the car and the car was not overheating.

We'll see what I find when I start ripping things apart this weekend!

Well, what you could do, is just take a water hose, spray it down like its raining, then check out where its coming from inside. If you tear apart the seal/weather stripping, you may not be able to put it back (so then, if you didn't need new weather stripping, you would need to buy some then).

I had this exact problem... i had to reseal a part in the engine bay... not sure exactly what the part's called, but i used some car caulk and created a new seal where the old one had dry rotted... totally fixed for really cheap, but if i could have replaced the seal, it would have been a lot more professional... but at least it was in a place that you can't even see, so it's all good so far... and no more mildew smell in my car after it rains!

I can see this "job" starting to cost some money. Just spent $250 or w/ Mikes Montes for a new rug and floor mats. The full door and TTOP seal kit is $350... I hate the idea of replacing the seals since there is a ton of threads/posts talking about how bad the replacements are. Heck... w/ $4 gas these days I barely drive the car!

After I pull out the rug I give it car the "old hose test".

aman555... Please try to be more specific about what you did/resealed. Was it the heater box area? Maybe take a pic and point to what you fixed!

THANKS to ALL!

Don't forget to check the gasket around the A/C box at firewall.
The gasket between the firewall and box is a long known problem on all G Body cars.
It will seep water onto the front passenger floor and "puddle up" at the lowest point (usually the passenger rear floor).
I found this out after mine sat for a year outdoors.
Cost me 1 cheap gasket, some sealer, then new floor and entire moldy interior.
Total invested to date about $3K because of one gasket!!!!!

Another good way to check for leaks is to run a compressed air hose from inside (only about 5 - 10 psi) and spray soapy water around EVERYTHING and check for large leaks. The tiny ones are no real problem as you are looking for a MAJOR leak.

So over the weekend I sprayed the car down to see if any water was getting inside through the t top/window/door seals. Not surprised to find that there was water on both side but more worse on the passenger side.

Thinking back, the car was parked outside all winter long, nose high on a slight incline. Lots of snow this winter in NJ.

Somehow I can't believe it was just the roof leaks that allow that much water to pool inside. A water-proof car cover would have helped a lot over the winter.

Some pics...

I am having a hard time keeping my hard top sealed, a T top is going to be worse and may never be 100% sealed tight without really tearing the car apart. G bodies have a lot of bondo from the factory covering sheet metal seams. This factory bondo is also prone to failing since it seems like just big globs of skim coat bondo. Once it fails you get difficult to trace leaks and rust. These cars are more bondo than steel from the factory.

I would bet that it is a seal issue with something in the firewall area and the water is draining towards the back and pooling up on the rear floor(s). Cars weren't meant to last much more than 10 years (if that even) or car manufacturers would be working themselves right out of a job. They want you to buy a new car every 5-6 years.
Our cars are 23-28 years old now and most are still relying on the factory seam sealer that has dried/cracked and is falling off in chunks.
Hate to see you spend a bunch of money on door/t-top seals that may not even fix your leak problem.
Sealing up the firewall area may not be a fun/easy job, but I can't see it costing even a small fraction of the door/t-top seals. JMO

Good luck, I hope you get it figured out and if you do be sure to let others know what 'seal' fixed it.

check the csulking seal around the heatercore/ac box where it joins the firewall. I had a small leak that drove me crazy. I piulled it out and regasketed and resealed. OK now. Also check the wire harnes coming thruogh the firewall just below the heater. seal that one too.

One thing I did not see mentioned was the windshield area.

My SS had rust issues (having been bought originally in NJ) and holes behind the windshield trim at the upper corners were letting water in. Down the windshield pillars and all over the passenger side floor. If you drive in the winter months, then add salt to the mix.

The rear foot well though, that's probably the t-tops, but don't discount the rear quarter windows, or the back window either. Water leaks are the most difficult things to track down at times. Good luck.

Just a few thoughts.
