My passender side floor stays soaking wet for some reason. My a/c is not draining under the carpet. Does anyone else have or had this problem?

 

I have read about problems with the cab brake light leaking. Might do a search about the problem.

 

Check the 3rd brake light. It could also be a leaking rear window. Also, the weatherstripping can channel water into the cab at the lower pinch weld.
I've had all 3 of these issues. I also had another issue with my 01 QC. A screw was missing from the weatherstrip retainer. It allowed massive amounts of water to enter a 1/8" hole and flooded the drivers side floor.

 

I fixed

the third brake light.. Solved that problem quick. Water enters up there, and somehow makes its way down to passenger side floor board..
