Hi guys,
I need some help with my truck. I parked it last night after work and the ac was working fine. Got in it this morning and no cold air.
It seems the compressor is not turning on and the condensor fan is also not turning on.
I have checked every fuse labeled for hvac and they were all fine.
Put gages on it and got 56psi low, 75 high for static pressure, it was 110 out when I did this. My understanding is that the static pressure should be much higher at this temp.
When I started the truck with ac on I showed 0 on the low side and 125 high side, but I don't think the compressor was clicking on.
My questions: does this just seem like a low refrigerant charge? If not, where should I be looking next? Seems like it'd be unusual to lose the refrigerant charge overnight.
Thanks for any help, it's way too hot to be without ac!
