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
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.
On a vehicle with a compressor with a cycling clutch, yes.
There may be some drag on the AC clutch when it is disengaged as the clutch 'free-wheels' during this time. When you engage the AC ,the clutch 'locks up' and the noise disappears. If the noise gets worse you may need to replace the clutch, if it stays the same and it not very loud, I would not replace it.
Could be clutch cooling fan engaging
how do you replace the AC compressor clutch on 2006 liberty
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.
This requires special tools to remove and install the ac clutch and bearing. The air gap on the ac clutch must be done during install.
Unplug the low side pressure sensor and run a jumper wire between the two terminals.
