01 AC not working
Ok, I bought a car 01 civic that AC wasn't working
troubleshoot noticed that it was missing a AC condenser
and the AC compressor was stuck. Replaced the AC with
new AC compressor, Condenser and air dryer and cleaned
all the AC line hoses. Putting all Back together and charged
the low presure but compressor wont engage check the
relay, good check all the wire connections getting my
voltage but when I try to jump the relay to start the
compressor wont engage so their is a problem somewhere
to why the compressor not engaging when jump from the
relay directly if anyone had that experience or know how to
fixe it please give me a tip to where to start troubleshooting
the issue I appreciate the help.
Thanks
Did you evacuate air out of the system before charging the refrigerant? Check fuses and the AC relay.
Yes, and both fues under hood and under dash are good, and relay is good as well swapped it as well when I check voltage from the relay 87 and 85 have 12v and no voltage from 30 to 87 correct me if I'm wrong voltage only applies when compressor engage right from those pins? Those are the pins where I try to jump to engage the compressor.
Thanks for the reply well I refuse the old one from the old dryer switch is there a way to test that switch if its stuck? Or is it best practice to buy a new one?
Thanks I'll give that a shot and update
Ok I jump the terminal on the pressure switch no go.. so went back to the relay..on the computer side which is is pin 85 have 12v to the computer and the load side should I have 12v on pin 30 as well..? If so that might be my problem not getting voltage on my load side..if that is correct if anyone can help me where to start maybe short to ground?
