I think this would probably be the best section for this. Feel free to move mods if im wrong.

MY 2000 rcsb silverado keeps having I guess a leak. The carpet, driver side, under my mats is always wet. Air conditioning on, off, heater on, off, windowns down, rains so much outside but still tends to be wet with dry streets. I have let it dryed before and it still got wet and no rain between that time period. No holes in floorboard.

Any suggestions?

 

how much soda is left in ur cup! just kidding, i can't think of anything that could be leaking. although u could have soaked ur carpet liner so bad that even though the carpet dries for a while, your only drying the surface so it gets wet again.

could be a few things-
1. after a while the door seal at the bottom wears and when water run down the cowl along the hinge piller it washes up and crosses over the seal.
2. if you've ever had the windshield changed and it was not done properley. WELL!
3. evaporator box could be draining in cab.
4. heater core could be leaking in cab.
5. you have a leak and your floors are wet.

i think its #5
hope this helps

 

also everything under their has a slight hent of rust.

 

It will be the seal in the door, mine had this problem and i have heard of alot of others also..
