Who knows about Rear AC? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

I charged my system thinking all systems were go and it cooled for a few days and went dead.

I found various leaks in the condenser and compressor, but my main concern is the Rear AC not blowing cold with the rest of the AC system. The fan works like it should, and the front AC blows cold as ice, but its like the freon wont go back through the rear lines.

I Dont know what could cause this other than that valve looking thingy connected to the rear evaporator. It seems like something is blocking the freon passage. WHY is this happening!? Anyone?
