Hi all, I have read many posts about this problem and have spent a lot of time and done a lot troubleshooting and apologize in advance for another post on this issue.
My AC is all new: (92 XJ 4.0)
new compressor, new dryer, new condenser, new high pressure lines, new fan resistor. Worked great for a couple weeks then all h**l broke loose.
I have done the trouble shooting: disconnect compressor blows fuse, disconnect blower blows fuse, disconnect low pressure switch use jumper blows fuse, disconnect low pressure with no jumper no AC but fan works and the fuse does not blow. I have checked all wires as best I could and see no issues.
So this is where the fun begins.
I am not that great with electrical so I took it in to an AC shop here in Rancho Cucamonga to have the wires/circuit tested. I told the shop that I felt the low pressure switch circuit or maybe the switch itself was bad. Shop does the testing tells me all wires/switch is good but says the blower motor is pulling too many Amps. I didn't want to pay over $100 to fix so I took it home and I replaced it myself. Guess what still blows the fuse.
I am fairly certain it is not the pressure switch because when using a jumper across the plug the fuse still blows, and based on what I have read if it was the switch using a jumper/bypass the AC should work. I have connected a multi-meter to various wires and all seems good till I test voltage on the low pressure switch plug. The Green wire side puts out 24V and the Blue has 12V. I am no expert by any means but I am fairly certain I should not have 24V anywhere.
If anyone has a clue as to what may be going on here please let me know what to look for???
If anyone knows of a really good electrician or AC shop around Rancho Cucamonga/Ontario I am all ears.
Thanks in advance, Mark
