I have a 2000 Blazer. The passenger side front floor pan, was soaked this morning. I isn't antifreeze. i think it is condesation from the air conditioning. I dried the floor and ran it this afternoon without the air conditioning on and it isn't wet now. Where should I look for the condensation coming from? Thanks guys!!

 

The evaporator for your AC collects condensation (water) which is routed through a rubber hose and drips underneath your vehicle when your AC runs. If this hose is clogged, it will back up into the evap pan underneath the evaporator and cause your symptoms. You may need to blow this out with an air hose from the end under your vehicle to remove the clog. Do you remember if you were dripping water underneath your vehicle in the past few times running your AC??

 

Thanks Tire Grit. Thats what I expected. I have searched for this hose and can not find it. Where exactly is it located? Is it accessiable better from underneath or from the engine compartment. Thanks!!
