The air conditioning compressor clutch relay is located on the bottom of the air conditioner compressor. The relay switch will be labeled.
Its in the fuse block - underhood.......
You cannot change the compressor bearing, however, you can change the clutch bearing. Which one is bad? Is there a noise when the clutch is engaged, or not engaged?
The bearing lets the belt pully free wheel on the compressor input shaft that the clutch is attached to.
If the compressor will not come on at all, it is not because the system needs charging. Check for a blown fuse, disconnected wire at the compressor, or a defective compressor clutch.
The A/C compressor is clutch driven, when electricity is applied to a coil, it engages the clutch. Most likely the coil shorted out in the A/C clutch on the front of the compressor.
Most automotive AC compressors use a cycling clutch compressor, where the clutch is engaged by pressure switches which will engage the compressor clutch when the pressure reaches a predetermined low level, and disengages it when it reaches a predetermined high pressure.
The clutch bearing for an AC compressor is located in the center of the clutch. If the bearing goes bad, then the clutch is replaced as a whole part rather than changing the bearing.
It is inside the under hood fuse box.
could be your a\c clutch in the compressor.?. or maybe pressure leaks.
The clutch has a bolt or nut in the center, connecting it to the compressor. After the nut is removed, the clutch can be removed by use of a gear puller.
Low on freon, faulty pressure switch, faulty clutch. Jumper the low pressure switch with a paperclip (can running, AC on), if the clutch cycles, it's either low on freon, or the low pressure switch is bad.
This happens to keep the fluid in the compressor viable. If it sits too long, it can become unusable.
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.
You have two relays, one for the a/c compressor clutch and one for the blower. The a/c compressor relay is located under the hood in the electrical distribution center. The a/c high blower relay is located inside the vehicle attached to the HVAC duct.
I'm having a hard time finding the bleeder screw for my clutch on a 96 Chevy Cavalier 2.2? Can you help?
Probably low on freon, you may have a leak in the system.
It could be a worn out belt, a bad pulley or even a bad compressor and or compressor clutch.................
If the clutch disengages properly then the compressor should not be running. Most likely the clutch itself is bad instead of the compressor.
There is a special tool that will pull the clutch assembly off of the compressor, available at your local parts store!
The ac compressor clutch is mounted on the front of the compressor and is a replaceable part. However depending on the complexity of the clutch change out it may be overall better to change the compressor and clutch together.
The AC clutch is on the front of the compressor where the belt rides. When power is applied to the clutch it engages to turn the compressor. It is basically a magnet a/c compressor clutch is the ound thing on the front of the compressor with pulley wheel attached. this clutch is an electro magnetic clutch that when electricity is supplied, engages so as the a/c compressor is driven ,which can then pump freon thru the ac system
Advice is to replace compressor the clutch goes bad only when the compressor goes bad on this model. They are sold to guys that rebuild compressors. Napa has the best price for clutches if you still want to try. Ebay there is a guy that sell rebuilt compressors for just a little more than the new clutch.
Possible causes could include: Failed air-con on/off switch. Wiring fault. Compressor clutch fault. Blown fuse. No gas in system. the clutch on the compressor has a fuse and it was blown. i soldered across the fuse and the clutch is now working. also if there is not enough gas the clutch will not engage as well.
The WAC relay is a solid state relay usually used to control the air conditioning compressor clutch.
