I have a '99 Chevy Custom van with an added rear AC (by A M Distributing). This AC uses the same compressor/condenser as the front AC, with separate expansion valve and evaporator. Had the AC serviced, front AC blows cold. But the back AC blows hot. The evaporator is very warm to the touch, but there line feels cold. Is this an expansion valve issue?
sounds like a low charge scenario-- have the charge level checked-- probably a leak.
The number one A/C diagnostic tool there is- is to know how much refrigerant is in the system- this can only be done by recovering and weighing the refrigerant!!
Just a thought.... 65% of A/C failures in my 3200 car diagnostic database (GM vehicles) are due to loss of refrigerant due to a leak......
This was immediately after having it checked and charged.
