Hey all, A/C issues again.
My compressor doesn't seem to engage when ambient temp is above ~105 F°, was told to check for an overcharged system. Hooked up my gauge kit, and static pressure is ~100 psi LP side, and ~110 psi HP at 95° ambient temp and 22% humidity. With compressor engaged LP side was 140 psi and HP was 150, which is obviously wack but was still blowing cold air?
Maintenance manual claims 60-80 psi static is the sweet spot but that was too low at this temp. Sounds like a stuck open expansion valve, however these vehicles have an A/C transducer which can cause a myriad of symptoms if faulty.
ForScan read my A/C pressure at 350 psi, which is way off. Service manual says this is a bad transducer. I haven't gotten any codes, so other than throwing a transducer at it what can I do? Thanks in advance!
