how to engage comp.
With the ac off your clutch the outer non belt driven part will not be turning. When it is turned on it will start to spin.
low freon
AC Compressor clutch relay may be stuck. Remove the relay and see if the clutch releases.
I am having the same problem. Brought it to an AC specialist and they told me it was my heating/AC panel switch that was going bad. The clutch would not stay engaged because the AC on/off switch was bad.
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?
Check the following............... 1. Freon levels. 2. Clutch to hub air gap. 3. Pressure switch. 4. A/C controller. 5. A/C clutch wire harness
Clutch possibly not engaged compressor maybe.
No ned to. Unless clutch is engaged (AC on) it freewheels-using no power.
Most Likely Low With Freon.
easy if you have put power to clutch from battery and system is in vacuum and centure of clutch is turning with the motor in means to say your valve plate is dead in side compressor.
The ac could be causing the problem. Turn the ac off, and watch the compressor clutch to see if it is not engaged. If it is then the compressor or clutch could be bogging the engine down.
The system is probably empty of freon. Running the pump manually without freon can damage the pump. The pump relies on the freon to carry the oil for lubrication.
