Guest gdiwicker Posted March 30, 2011 Share Posted March 30, 2011 So I have clear floor mats and when I'm driving for 30 plus minutes, condensation builds under the floor mats. I think since I had motor mounts installed, the exhaust got raised closer to the car and is causing the heat transfer. Would having the exhaust bent or modified vs installing a heat reflective material (lizard skin, dynamat) solve the problem better? Link to comment Share on other sites More sharing options...
Rawja Posted March 30, 2011 Share Posted March 30, 2011 Wouldn't the condensation mean that you're evaporating existing moisture from your carpeting?? I think you should be looking for the source of the moisture rather than lessening heat transfer. Link to comment Share on other sites More sharing options...

JZRIV Posted March 30, 2011 Share Posted March 30, 2011 Yep, better investigate deeper. Lift the carpet. Its probably wet underneath from a water leak. Link to comment Share on other sites More sharing options...

MCHinson Posted March 30, 2011 Share Posted March 30, 2011 Not sure exactly what year we are talking about but another possiblity that I have seen on another GM product of the 70's or 80's is an air conditioner drain being plugged. It caused water to run down the firewall and under the passenger side carpets. Link to comment Share on other sites More sharing options...
Guest wildcat465 Posted March 31, 2011 Share Posted March 31, 2011 You got moisture under there. Check afore mentioned items, add windshield seal and body seams to the check list. I hate saying it, look for rust hole in floor. Get it fixed, or your next problem is a nasty smell, caused by mold. Even tougher to fix. Link to comment Share on other sites More sharing options...
Guest gdiwicker Posted March 31, 2011 Share Posted March 31, 2011 OK more details.64 Riveria 425When I did get the engine mounts replaced, the other after effect was that when I'm in reverse, the the PS exhaust rattles against the undercarrage. It builds up no matter if I have the ac, and heater off or on. It also doesn't matter if it hot or cold out and I never take it out in the rain.

steelman Posted March 31, 2011 Share Posted March 31, 2011 ...and I never take it out in the rain.Do you wash it? Car wash or garden hose or rain, water is still water. If you have a windshield leak, it will get just as wet inside from washing it with a hose as it will being in the rain. Link to comment Share on other sites More sharing options...
Guest REX STALLION Posted March 31, 2011 Share Posted March 31, 2011 Heres a odd one, the vent system under the fenders is a place that can rust through causing water to seep in through the fresh air vents. Look for the obvious first as removing the fenders is a bigger job. Link to comment Share on other sites More sharing options...
