Usually, on most cars, this means that the weather is cool or that there is insufficient refrigerant in the system. It can also be caused by a restriction in the AC system or high temperature or excessive amount of refrigerant in the system.

What happens if the electrical connector is not connected to the ac compressor?
The a/c clutch will not engage and the compressor will not come on.............
If the AC compressor clutch does not kick in and the relay and fuse are ok what could be the problem?
The clutch receives it's signal to engage from a pressure switch in the system. If there is insufficient refrigerant in the system the pressure switch will not close resulting in no power at the compressor clutch to make it engage.
How do you know if AC relay is bad?
Turn on ac and watch clutch on front of ac compressor. If clutch doesn't engage then AC relay is bad. Or you can follow the schematic on the side of the relay and use a volt meter to test it.

What caused an air conditioning compressor to turn on or off?
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.
What is an AC compressor clutch and what does it do?
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
Ac compressor clutch 2002 ford focus?
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.
How do you engage the AC clutch to refill the system?
You don't need to engage the compressor clutch to recharge the system. In fact, you shouldn't engage it without refrigerant and oil in it, because the refrigerant carries the compressor oil in order to lubricate the compressor. But, to answer your question, you disconnect the low pressure switch, and run a jumper wire between the two female ends of the connector.
How do you test the ac compressor?
You should be able to hear it engage-there is a clutch. If not, check the hot wire when someone turns on with a test light. If it has juice & does not engage, you may have a problem.
How do you fix an air condiosoner pump because it does not spin or work?
Do you mean that the AC clutch does not engage the compressor? Or do you mean that the AC compressor won't turn even if the clutch is engaged? If the compressor is siezed and will not turn even if the clutch is engaged, the only choice is to replace the compressor. If you can turn the compressor by hand (understand that the belt pulley will turn freely with the engine if the clutch isn't engaged) but the compressor clutch isn't engaging, it might just be out of refrigerant. There is a sensor, usually somewhere near the receiver/dryer) that detects the "low side" refrigerant pressure. Once the refrigerant pressure at the sensor drops below a specified level, the compressor will not turn on. In other words, if the compressor clutch won't engage it might just be out of refrigerant.
Do you have to discharge the ac when replacing AC clutch?
no, unless u have to remove the compressor unit. The clutch can be replaced with out removing the compressor if you have room to do it.
Why does idle jump when air conditioner is on in a 1991 dodge stealth?
does it jump or fall? when you turn the ac on theac compressor engages. the ac wheel is always turning when the engine is started but when the ac is on the clutch plates in the wheel engage and the inside of the ac compressor turns an yata yata u get cold air. when the clutch plates engage the engine has to work a little harder to run the ac so the rpms change, and you mpg usually does to.
