Yeah yeah. I know real jeep doesn't have a/c. But. I use mine as a dalie driver and I got a 1 yo. Now that said. I replaced my compressor cause I know it was broken. Now The a/c cluch won't kick in Ive check the relay and the a/v control panel in the dash. What am I missing. I'm not getting voltage to the compressor so I know the problem is behind the dash somewhere. Help please. I'm time limited on this obe

hey
srry im not giving u a solution
im actually looking for the same solution
i replaced the compressor, but can only get it to kick in by
manually closeing the relay or jumping the power tabs
seems to be a dim light on one side under the relay w a test light
dash switch also seems to be working the idle picks up a bit when i turn it from off to air and relay in side power goes on/off w switch
i also tried a cpl different relays w no luck
seems we have the same problem
hopefully someone here can help

I wasnt getting power to my comp. and I replaced my low press. switch and all is good now. Just know the motor has to be running to get power to the comp.. You can bypass the low press. switch if you want but I got one for around 5 bucks.

you unplug the switch and make a jumper with 2 male spade connectors on it and plug them in where the switch was.
