My chevy air conditioner is not good. The front is warm while the back is cold.. Before 2 months I changed the compressor with cleaning the circulation. Also before 5 months I disconnect the heater hose because it was leaking..

Any idea to track my problem

 

Have you checked the blend door actuator? Seems to be a common issue with this hvac system. Your symptoms sound just like it has failed.

You can remove the actuator and leave the electrical connected change the temp selector and see if the actuator turns. Also, you can manually open and close the door once the actuator is removed to see if the temp changes coming out of the vents.

 

When I disconnected the the heater the ac work only on cold even if the bottom on heat area.. (I'm ok with that I don't need the heater)


Do you think the problem from the evaporator?

 

the problem was from the low presser valve it was leaking...


i changed it and refill the Freon now it is OK
