So the other day after driving to work I went to add more washer fluid to my reservoir. After opening my hood I noticed that my entire AC line was frozen white. At the time I just assumed I was low on Freon. The next day however after inspecting further I noticed that as soon as my vehicle started, my AC clutch immediately engages and starts spinning, even with the AC knob in the cab set to off. At first I assumed it was my pressure sensors, when I removed them with the car running the clutch still did not disengage. My low side seemed to be bad due to there being no ohm reading so I replaced it, still no luck (even when unplugging the sensors it still stays engaged). My relay in the fuse box seems to work fine, in fact the only way to disengage the clutch (without turning the vehicle off) is by pulling the relay out. I even hooked up pressure gauges to see if my low and high levels were right and they were, meaning my Freon is good. One other thing to note is that when turning the AC on and off in the cab the fans and stuff inside respond accordingly, as well as the pressure levels on the gauges.
To sum it up, my AC never cuts off unless pulling the relay or turning the vehicle off. The clutch isn't frozen and it can still disengage, it just doesn't when I turn my AC off. It's not the Freon, it's not the relay, and I don't think it's my sensors. Does anyone else know what it could be? Thanks.
