I have a 00 Chevy 1500 suburban lt. The floor behind the drivers seat is getting wet periodically. No rain and I've not used the AC in a while. No drinks have been spilled and there is no smell from the carpet to indicate coolant or whatever.
Anyone have any ideas what I should look for or the cause of this?
​​​​​​​Thank you

 

If no rain, have you gone through a car wash recently? if not how about water puddles ? It's possible the water is coming up through the floorboard, you might have a body plug that has rusted our or a bolt hole that is not sealed...

 

No car washes but yes to small water puddles. Just been damp roads and a few puddles from yards being watered. I will check for those issues when I can pull the middle seats out and pull the carpet up.
I was hoping someone has had this issue or had seen this before and could help. Thank you.
