Wet passenger side floor

**Silver GTS** · 04-22-2017

I have had a water problem with my 98 GTS on the passenger side floor. I have searched the forums and have tried to clean the a/c drain tube with a wire, garden hose , and a low power air compressor. Any other suggestions I would really appreciate it thanks in advance and sorry to bring up such a old thread

Just to make sure, you had not driven it in the rain or washed it?

Sounds like you may have a leak from the small heater radiator in the car? Can you smell Coolant? Sort of a sweet smell usually.

Check the foam seal where the heater hoses go into the heater core. Open the hood and it's above the passenger footwell right by the heater core valve. That foam can deteriorate over time and leak water in.

Thank you all for helping me out with this problem I really appreciate it. Just wanted to answer a few of the questions some of the guys asked. The passenger side of the floor would get soaking wet if I left her outside even with the factory car cover on it especially if it rained very hard. The car doesn't have that antifreeze smell going on so I don't believe it's a leak from the radiator system. Dave6666 mentioned something I have not looked into regarding the foam seal deteriorating around the hoses that go into the heater core. If that's what's causing my leak what do you recommend to fix it ? Can I order new foam or should I use silicon. Thanks for helping me out with this problem

Perhaps you scared your passenger to the point they relieved themselves?

Interesting theory...might want to look into this one

The foam is no longer available although you could make a piece that would work. The problem is the disassembly needed to get access to that area is somewhat huge.

Using an RTV sealer from the outside would be way easier if you decide that's the entry point. Very odd that it comes through a car cover tho. Yet the rest of the car does not get wet?

BTW, "silicon" is a rock hard element (Si) that they use to make computer chips. Silicone is what RTV sealants are called.

Here is that seal from a spare HVAC box I have. It goes inside the part you see with the hood up. Relatively big job.

**ssmith71** · 04-23-2017

If if is from rain, check the seal around the rear of the window near the B pillar trim mounting point. That is where mine leaks in the rain and gets the floor wet by the foot well.

Hi, this is Ed Adamchek, new member of New England Region, and I had a similar issue on my driver's side, back in 2007. Since my car is red, I bought some red silicone hose, approx. 3/8" I.D., then by using mix-n-match hose couplers, similar to vacuum line splitters or connectors, I connected the hose to the drain from the cosmetic, screened, left side hood depression (I think I used a 90 degree connector. Then, using Goop Advanced Automotive or Goop 6000 (I LOVE THAT STUFF) and some high-quality duct tape, I secured the hose to the underside of the hood, down to just behind the left wheel well, Gooping a section, then duct taping it into place, about 6" at a time, cutting the tubing to end just 1/4" or 1/2" above the bottom hood edge, and draining down into the side-exhaust cover. Haven't had a wet ankle when caught in the rain since. Hope this helps P.S. Drive the car for a few days before carefully removing the duct tape & then either a solvent or penetrating oil to remove the duct tape adhesive left behind.

Those go in from the inside don't they?

**Silver GTS** · 04-25-2017

I want to thank everyone for all the great tips and suggestions including photos/diagrams very cool of you all. I drove the car about 60 miles on Sunday and checked the passenger floor & the HVAC system a dozen times and it stayed dry. I have the car outside with the factory cover on it and it's supposed to rain hard for the next few days, I will keep you posted and let you know if I get any water problems & will use your suggestions to hopefully fix this problem

**My98RT10** · 04-25-2017

Glad you fixed the problem! One other question comes to my mind reading your post: is the factory car cover designed for outdoor use? I always thought it is not....!? Thanks.
