Damp carpet and further investigation of wiring


Recommended Posts

I noticed a small damp spot on my carpet the other day(it's been raining). I am suspecting a body plug or something like that is loose on the underside of the car. I decided to take out the seats and check the wiring in those raceways on the floor. Fortunately, all was well, however, I had heard someone telling me of some wiring nightmares starting with dampness or water getting ito those chanells. That's why I checked further. Just passing this along to anybody, as it looks from my wiring diagrams, that this is a BIG DEAL bundle of wires. Having said all that, does anybody know of any suspecious plugs under the car that should be checked. I have no hoist anybmore so i"m on the creeper....Boo!

No sunroof. The dampness was in the middle of the passenger side carpet and I only noticed it as I lifted up the mat to clean it.

It is possible, even probable, that the passenger window was not completely up. I had this happen in my 91 coupe. The passenger window was open just a quarter of an inch or less. The rain leaked to the inside of the seal and dropped to the floor behind the seat. I found standing water inside the next day about 1/4 inch above the carpet. Used a wet/dry vacuum and no damage was done. I have found that the passenger window will not close completely using the switch on the driver's side but will close using the switch on the passenger door. This occurs in both my 91 coupe and 91 convertible.

So the weather dried up and the wet spot in the middle of the carpet was gone.

I really believe there is a body plug that is missing or deformed and needing replacement. I have to get the car on the rack to be sure.

Too much water coming in from the road could kill these cars, I believe.

That is based on the number of wires in those raceways. Then they added insulation around the wires just in case you wanted a "water wicking device" to pull the water into the wiring. At least it wasn't a heater core as Marck mentioned. I don't need any of that action!

You might want to take a water hose to spray the area around the glass and the rubber seal, they are deteriorating and are unobtainium. Some times you can put inexpensive 1/4" vacuum tubing between the body and the rubber to push it out to make better contact.

Tony,

Attached are two photos. One shows the underside of the passenger side of an '88 Reatta. In it, you can see a body plug just above the right side jack stand. It is the slightly rusty oval. The other pic. shows the same car, looking from the front into the passenger compartment. If you will look at the lower left of the shot, you can see a rusty splotch near the same oval body plug. This may or may not be the point at which the water is getting into your car.
