Hey Guys, I'm sure this has been posted or something similar, and I've also posted in a separate thread on here, but figured I'd post here as well.


I had noticed slight dampness and leaks before and adjusted the driver's side window, but after several days of heavy rain I discovered this on both driver and passenger's sides of the car. Under the driver side floor mat was totally soaked. How do I fix this annoyance?

This is an 03, Z06 by the way







(Ok I lied it's on both sides)

 

Your best bet is to remove all the plastic coverings and then get in the car and have someone wet the sar down. If theres a leak, you will be able to better see it and where its coming from. I had my passengers side GUTTED to find mine.

You may even need to remove the carpet.

My free time seems limited these days. Think it's something the dealer would be able to fix easily? Or do you think the dealership would be too focused on just trying to get an insane amount of money?

 

I can't say thanks enough Bill. You did a really excellant write up on a common Corvette problem. I even had 'Ground problems' 35 years ago with my first Corvette, a 1959 which has the same kind of a problem as you experienced. So grounds are a problem that flourish with Corvettes. Thank you agine for your excellant work.

I have a 2003 corvette there is some king of oil leaking onto the top of the rear axle on the drivers side. Does anyone have any idea where its coming from? Ron

 

Thanks Bill for this write up. My 2004 that is garage kept, never driven in the rain and pampered beyond belief was chocka-block full with dried leaves and other debris in the 3 "udders" on the driver's side. I then removed the battery and took out the "anaconda" udder and it too had some debris in it. I will make this park of my yearly PM on this car.

The AV Evapaorator udder I could not get to from the top side so I'll bring the car to one of the service pits nearby and give the guy $10 so I can inspect it.......but I'm not to worried as I do get "dripage" when I run my AC.

Thanks Again Bill Curlee, you are the man!!

 

Yes you can. It isn't pleasant on your knuckles but it is doable. Unless you have gigantor hands. Agreed, Bill is the man.

 

1st vette, 1st road trip, passenger floorboard flooded. Been reading up on the leak fixes. Pretty sure mine is the AC drain that you can't get to. Milked the udders and on the very rear one, you know the one you think is not there, I got a 5/16 or 3/8 nut out of it. Not sure what to make of that. The rear one was the most trashy of the three.

As to the black anaconda hose I think I saw where Bill said to just unhook it and shove water through it with a garden hose and do not remove it from its position?

I think I had a finger on the AC drain 90 degree hose but not sure. I guessing putting it back on from the top would be harder than removing it. Is it really easy from under the car? Anyone?

Thought I would just raise the car up last night and then read the jacking the car up thread and now I'm almost afraid to even try and raise the car at all. If you raise the car with a hockey puck enough to get under (with jack stand support) to take the AC drain hose off for cleaning will the car break?

That got me looking at 4 post lifts. Gonna be a damn expensive drain cleaning. Worse than calling a plumber!

If someone could just weigh in on the Anaconda flush I sure would appreciate it.

i have a 2000 convertible which leaks at the rear of the floor on both sides. i have cleaned the drains in the front and do not get water in the front of the floor. any idea where this leaks?

 

Just another big thanks to Bill for his remarkable contributions to this thread. I just replaced my blower motor due to the backup from the AC bladder and didn't want the same thing to happen again.

Haven't been on Corvette Forum in years because my baby just sits and never gives me problems. (Only driven about 500 miles each of the last 4 years) I used to be a freak enthusiast and started modding my 00 vert as soon as it was delivered to me in April, 2000. But it sure is nice to know this site is still here. Does Tony still own this site?

i have this problem, with the water in the passenger footwell after using the AC. the firewall drain tube does not seem clogged. should i try to put a wet vac on the drain tube (after trim the opening)? should i run the AC first to have something to vacuum?

thanks

 

The 90 deg rubber fitting pulls off the plastic fitting:







Just remove it and see if you can feed a modified long thin tie-wrap into the hole. I cut backward facing teeth into a tiewap shoved it into the drain hole and pulled out the crud that was blocking the hole. You can also use compressed air and dry to dislodge the crap BUT,,,, this just moves it back into the air box for future issues. If you use air, remove the fan motor and see if you can use your hand and retrieve the trash.slime.

thanks for the info Bill. i finally did get the rubber fitting off (had to push a wire bundle up out of the way) but the modified tie-wrap nor the shop vac got anything! i think its clear... so why else would water come out of the passenger side footwell vent when the AC is on? is there a bad seal somewhere maybe? this has nothing to do with the 3 drain utters i read about, does it? it's a 2000 hardtop. thanks

 

The water/condensation drains out a small drain hole and thru that drain pipe. If it clogged,,,,,,,, its GOING to drain into the foot well .. No doubt about it.

 

You are correct! I was getting a lot of water in my passenger compartment. I have removed the carpet a few days ago. Today, when checking for leaks, I found this hose looking exactly like your picture: DISCONNECTED!

 

I have an 03 z06, When it rains I get water leaking by the A pillars. I haven't removed the interior and leak tested it yet, but when I was doing a visual inspection and making sure my drains were clean. I found the seal behind window moulding has like an 1.5-2" section missing. I just want to make sure that seal is sapost to keep water out and this maybe my issue. Here is a pic




Also my trunk gets some dampness in 3 storage areas. I poured water in the channel and it drained so i think the drains aren't clogged. Anybody have any experience with a trunk leak?

 

just sealed my driver's side hinge with black silicone. that did the trick. all the heavy rain in maryland this week was a good test. no more water dripping into my shoes. lol.

 

Ok this one's got my stumped . I know where the leak is coming from, my problem is, I haven't been able to stop it. Long story short we had a ton of rain yesterday in the Mid-Atl region, I was working on my house today went to grab something and found the carpets soaked. I pulled out both seats, propped the carpets and let it dry (goodthing the humidity was 50% today).

I've pinpointed the leak to where the rear of the targatop where it meets the B pillar. The kicker is, I've already replaced the "halo" weather stripping just a few weeks ago. It looks like it seals but when I hit it with the hose, it leaks. I then started playing with the adjustment of the top, making it tighter etc, it was wierd, sometimes I got one side to seal but then the other side will leak. Other times both sides would leak. Ugh. Any other tricks besides keep playing with the adjustment of the top?

I got sick of adjusting the receptacles (the things that look like cones that take the "*****" on the back of the targa top), putting the top back on, hosing it down, going into the car, looking only to find a leak. Wiping it back up, repeating the process. Probably spent 3 hours doing this

I should mention this was the clear top which is a relatively new one (bought from another, newer car). I have not yet tried the body colored top which I have at a different location. Soooo, any tips for a leak where the back of the targa top meets the B pillar on already replaced weather stripping? I will post pics tomorrow but hope someone will see this in the meantime...

 

Have you tried to adjust the top by adjusting the hold downs?? Heres the service manual procedure:

Roof Lift Off Panel Adjustment
