So my A/C stopped working.
Took it to the shop and my mechanic filled it with Freon and dye because there was a leak.
Now the compressor will not kick on even though it has power to it.
He told me to replace the low and high side relay and see if it will work then.
Anyone have any experience with this?
He seemed very hesitant to take the job on not sure why?
Sounds like the low pressure switch. I had the same thing once and that is what it was. The low pressure kicks it on to raise the Freon pressure and the hig switch cuts it off when it reaches the correct pressure.
Sorry to hijack, but my a/c stops working, then turns on some times, mostly not. I might try that relay, were is it? I figure my charge is good since it still kicks in periodically.
Coming off the control panel, it only goes through three things, the hi pressure switch, lo pressure switch, the relay (in the ccrm), and on to the compressor. If you have voltage at the compressor, check your ground. One wire in the connector is power, the other is ground. If power and ground is good, the compressor is bad. If power isn't good, you can install a jumper in the wiring across the above three things and see I'd the compressor kicks on. If you need diagrams or wires/pins, let me know.
