I have a 2001 Yukon. My floor board was soaked under my front passenger and back passenger floor matts. I brought it to somebody to fix, they said the drain pipe was clogged. Charged me very little to fix but I'm not sure if it's completely fixed. The front has completely dried out but the back still has a small wet spot along the edge that I can't get dry. Any ideas why the majority would be fixed but not that one spot? TIA

find drain hose (usually located near firewall underneath) and suck out with shop-vac.

The drain hose will exit the vehicle near the cowl directly to the ground.


OP, look under the truck near the front passenger door area. Run a straightend coat hanger in there and clean the gunk out. Also look under the dash are and be sure the tube is still connected, although I would imagine they checked that.

Sounds like a head gasket issue. If youre experiencing moisture from the inside id get the heads looked at by the means of a compression check to see what the current PSI levels are at.

This!

I recently had this done to my home a/c. The overflow flooded my garage.
