Having AC problems. I was told that the issue was high
I was told that the issue was high pressure on high side and was told that I would need to replace condenser and dryer. Before I could replace my wife drove the car and blew the high pressure hose off going top condenser. I di not do anything for a year and decided to do the repairs myself. I replace the hose, condenser and dryer. I then vacuum the system for 3 hours and attempted to add freon. The max pressure i could get was 35PSI on the low side. The clutch was short cycling and when the compressor comes on the low drops to almost zero but the high side stays at rough the same PSI as low-35psi. My question is the compressor bad or the expansion value. It is a 2002 Volvo and to replace the expansion value it is a total removal of the dash. Desperate for help and advise … read more

2012 Mitsubishi Lancer 130k miles. A/c stopped working. I
A/c stopped working. I replaced the expansion valve, didn't help. I noticed the high side pressure was too high so I replaced the condenser, vacuumed the system, and recharged. Now the a/c works, hi and Lo pressures seem right, blows cold, but the compressor clutch cycles every 10 seconds. Clutch engages for 6-10 sec, disengaged for 6-10 seconds at idle. It's even worse when driving, when I apply gas, it cycles every 4-5 seconds. I found out that it's the evaporator temperature sensor (thermo probe) that keeps disengaging the clutch at 32F degrees. According to the car's specs, when the temp sensor sees 32F, it tells the ecu to disengage the comp. clutch, which is exactly what it's doing. Why is the evap getting so cold? Temp out the vents is 40F. But the clutch is cycling too frequently (every 5 seconds when driving). I understand the temp sensor is disengaging the clutch so the evap doesn't freeze over, but the cycle time is way too frequent. Why? … read more
