Ok, I just moved from Alaska to Oregon, and I noticed somthing new. While driving in the rain, my feet get soaked. I looked in the cowl and didn't see anthing unusual, It would be more of an inconveinance than a problem, but I think some of the wiring behind the dash gets wet. Any ideas?
I had water pooling in the floor boards of my 89 a few years back, turns out the windshield was leaking at the bottom of the glass and had to be resealed.
Most good auto glass places have an ultrasonic leak finder that finds leaks without a lot of time and effort. If you want it fixed fast and easy, it the best route to take. If the windshield has to be removed to reseal it, I would definitely let them do it.
