Hello... I'm having a problem with my Lexus GS300 (1998) that's been driving me nuts. I have taken it to the Lexus dealer 3 times and a non-Lexus dealer once...nobody can find the problem. Here is the problem:
When the A/C runs, I get a lot of water that builds up under the carpet on the drivers side. Not just under the floor mat...but all the way into the back seat. I have taken out the driver's seat and pulled the carpet back completely on the drivers side (including the carpet in the back seat). Its soaked (puddled water) all the way back. It doesn't appear to be coming down from the front firewall area. While the carpet is back, and the A/C is running - I can't see moisture coming from anywhere. The Lexus dealer cleaned out the A/C drains and the drain from the sunroof. Didn't help.
Any thoughts? Someone posted something earlier in reference to a leak in the steering column. Thats not my problem. I'm convinced its related to the A/C. I'm even thinking now that its origin isn't the front seat area, but somewhere under the seat or behind. There is a vent under the seat, but it doesn't seem to be leaking moisture either...
Its frustrating that I can't recreate it with the carpet pulled up. Perhaps the car needs to be in motion for this to happen (?)
All comments welcome!!
Thanks for ANY ideas...
