Stuck open TXV, bad compressor, ...?
Posted: Mon Jul 01, 2019 5:17 pm
Hello all, I am working on a 2007 Toyota Camry 2.4L with inoperable AC. Here's the details
~85-90F outside, high and low side pressures both the exact same at about 145psi. I have 13v going to the compressor with the AC on, and I have verified 0 ohms resistance from ground wire connector to engine ground. So, I have power and ground going to the compressor, fans are both on as they should be, yet absolutely no change in high side and low side pressures. And yes, I am certain that my gauges were hooked up correctly. Also, this vehicle has a "variable displacement" compressor, so no clutch!
Where do I go next? My thoughts tell me a stuck open TXV, but even if it were fully stuck open, I would expect some type of pressure differential. Failed compressor?
Thanks in advance!
