AC Fuse

Ive been looking all over, and I cant seem to find the fuse for the Air Conditioner for my 1988 Cherokee Sport. I really appreciate your help! Thank you! :smile:

I don't see a fuse for the a/c clutch in the manual, there is a relay, maybe the relay is fed with a fusable link. I see a diode at the a/c clutch, maybe that is what is used for protection. Is the a/c clutch getting power???

I tried to switch the relays, they work, but the compressor does not switch on.

it could be low on freon, the clutch will not turn on if it is low, the low pressure switch will not let it run.

How can I bypass the low pressure switch to make sure the clutch works?

unplug the low pressure switch and jump the two wires together. This should turn on the compressor, and will bypass the switch. Good for test purposes and for filling the freon, if you do it yourself.

Sorry i'm such a noob, :uhoh: but where is the low pressure switch at? I can see that there is two wires on top of the compressor, but i don't see a switch to unplug. I need help. Thank You!

It's not on the compressor. It's on the receiver dryer just below, right next to the sight gage. DO NOT REMOVE the switch, just the connector.
