2000 durango front vents hot, rear ac cold? help...

The first thing to check would be the proper charge of r-134

I took the truck into a shop and had them connect it to an ac testing unit. the shop said the system was properly charged and the compressor was bad. they recommemended replacing the compressor, dryer, expansion valve, and engine cooling fan clutch...... did not seem to make sense to me, since the rear ac blows cold.... so I posted here for other ideas / suggestions...

someone else mentioned checking the blend door or actuator.... any idea on where they are and how to access them? How would I check them?

If both hoses coming off the compressor are hot how can the a/c be cold??????? the low side of the compressor should be cold and the high side should be hot.you said both hoses are hot?

Very good question. I'm not sure why the metal hoses feel hot to the touch, yet the rear ac unit in the rear is blowing cold air. There is a "T" junction near the truck's firewall (on engine side) and the metal pipes to the rear drop down to the frame and run aft to the door frame and then up to the rear ac unit.

suggestions...

either way a low charge will cause thiis problem

Thank you for the reply, please forgive my ignorance. Wouldn't a low charge cause both front and rear to blow warm? why would both pipes be hot and yet the rear still blowing cold. It is beyond my simple understanding... which is simply... one cold pipe moves cold freon to the coils, fans blow air over the coils to cool the air, the warm freon returns to the compressor after going past the coils near the radiator.... so if both pipes are hot, why would one set of coils be cooling the air?

could there be a blockage in the pipes near the front set of coils, or bad blend doors / actuator motors?
