95' V8 a/c not working
I have a 95 Grand Cherokee Limited V8, which the a/c is not working I have checked fuses and relays all are good. (I swapped the ABS relay with the a/c relay no change in either one) I used a can of refrigerant from AutoZone and the gauge is in the charged area. I know that the once the compressor kicks on the reading will go way down, but the compressor is not engaging. there is no audible "click." I can turn the center of the pulley by hand which means the compressor is not frozen? This tells me that its either a sensor or the signal is not getting to the compressor to tell it to engage.
I have 2 wires coming from the compressor that look a little shady. 1 White, the other black. The white wire leaves the comressor and continues to a small harness where it connects to another wire, then disappears into a bundle of wires. The black wire is only about 6 inches long it leaves the compressor and is screwed in to the compressor mount (some one grounded this wire, I can tell this is not a factory ground). Any ideas? is there a way to test the sensor and wires? Where are these wires, that come off of the compressor, supposed to go? |

Jump the low pressure switch and see if the compressor kicks on.
|
Where is the low pressure switch and how do I jump it?

K, I will give it a try.
|
You know where it's at don't you? If not I can send you a PM showing you. Let me know.
|
finally got time to try jumping, when I jump the switch the a/c turns on, I replaced it and now the compressor makes a horrible noise. I am assuming that it is bad. The question is, is it something I can rebuild or do I need to fork the money for a new one

Mine acted alot like that when it was low on freon, had a split hose. Thats why the pressure switch shuts it off. I tried to add like you and the supplied guage was also telling me it was full. Anyway I had it died and found the leak, had a shop replace the hose and have been running cool all summer now. Cost me some money but thats just the way it goes sometimes. At least I got it fixed the first time. To mee AC systems are no place to parts swap.
