I have a 04 trailblazer that leaks water on the pass floor when the a/c is running. The a/c blows cold and everything works but just pooling water.
Does anyone know where to find the evap case and the drain hose for the a/c or have a pic of them. Oh and I checked to be sure and it is water and not coolant.

 

Drain is plugged up on the evap core. There should be a drain hose that allows condensation water to drain to the ground, look for that it is plugged, and water is draining on your floorboard.

 

Thanks but i already knew one of them was clogged, I was asking for the location of the drain line lol. Its all good though I found it yesterday and when i pulled off the drain line about 1 1/2 gallons of water came out. Everything is good now. It was on the pass side firewall right next to/ below the a/c lines.
