Refrigerant Type: 134a
Ambient Temp: 90ÃÂ°
Country of Origin: United States
Daughter told me the a/c quite working. hooked a pressure gauge to the low side and started the a/c and the pressure never moved. changed the compressor and added 3 cans of freon and started the a/c and the relief valve went off. noticed the low side pressure went in the red when the relief valve went off.
Did you change the accumulator, check/change the metering device, evacuate the system? What is the high side reading? Did you put the factory charge if freon in the system?

08 avea calls for 19 ounces of refrigerant. 3 12 ounce cans is 36 ounces. YES, I know all 36 will never make it to the system, but if charging from cans (not recommended) I would have stopped at 2. Being overcharged would explain why it is "relieving" and the low side pressure is "in the red." Having the system evacuated and recharged with the proper amount of refrigerant is where I would start.
I bought a can of 134a at w**-mart that had a stop leak, oil, and dye in it. It also had a hose and a gauge, so now I'm an AC pro!
Was the original compressor engaging? I'm just having trouble understanding how you came to the conclusion that the old compressor was bad.
I'll just bring it to an expert.
