Random Passenger Floorboard Leak

Good afternoon all.

About two weeks ago when I took my truck to the carwash, I pulled up my floor mats and on the underside of the passenger floor mat it was completely soaked. It hadn't rained for quite some time and I hadn't yet gone through the carwash.

Since then I have left the floor mat off on the side and water is continuing to soak through. It is right in the middle and has no apparent source on the inside of the cab. Any ideas?

 

You have AC right? I'll bet the drain hose has separated from the box. look at the very front of the passenger area, and pull back the carpet a but and look up at the floorboard. If there is no hose going thru that hole, there it is.

(Or it's Clogged )

 

Check any grommets on the firewall inside the engine bay to see if any have popped loose. Mine did this on the driver side when routing some wires.

 

Well?

 

Are you loosing coolant? Your heater core may be leaking.
