What specific kind of vehicle do you have? It does sound like the clutch may be bad, but we also need to know what you are working on. You need to run power straight from the battery to the compressor. If is still does not engage then you need to replace the compressor and clutch, they are dead. If they do engage, then you have a wiring or computer issue.
Oiling the a/c clutch will cause the clutch to slip and burn up........
I'm Guessing that your talking about the A/C compressor, in which there are 1 or 2 wires going to the clutch. Disconnecting this wire(or 2) will disable the compressor clutch stopping the compressor from working.
The A/C compresor is low on the front of the engine, up inside the engine compartment. I have never heard of a serpentine blt "bending" a pulley... When an idler pulley bearing fails and siezes, it will break a belt. This is most likely the cause of belt failure. If the A/C compressor drive is not turning by hand, this is most likely the cause. There is a bearing on the nose of the compressor that allows the hub to rotate and "drive" the compressor when the clutch is activated. The A/C clutch is replaceable without replacing the entire compressor assembly. Check all the pulleys and make sure another one is not also failed.
Maybe the compressor clutch is not being sent power from the switch in the cab. I'd yank the panel out and have a look at the switch. FriPilot
Yes, if the compressor's bearings are bad, usually accompanied by a roaring or squealing noise coming from the compressor's pulley.
Low or no freon will cause the AC not to work. Also if the clutch on the AC compressor has failed, or if the compressor itself failed.
I had that problem in my1998 CR-V and took it to a mechanic... Was told that my ac compressor was freezing up. And that if I kept running my ac it could cause lockup.
A slipping clutch may cause cracks on the flywheel wear surface from excessive heat. The cracks would be reason enough to replace the flywheel when replacing the clutch assembly.
Check the clutch and see if it needs replaced; more then likely the compressor came apart on the inside and you'll have to replace it, flush the lines, and replace the orfice.
Any of the following.......... 1. The compressor is locking up. 2. You have a bad a/c clutch. 3. You have a bad drive belt. 4. You have a bad tensioner. 5. The a/c system is overcharged.
could be several things. the signal comes from the switch on your dash and follows wiring to a relay and more wiring to the clutch. you are bypassing all of that when "jumping" the clutch. if it works when jumped the clutch is good. get a test light and check the wiring to the clutch. good luck....a/c wiring sucks
