See if hot wire hot with switch on.
An air conditioner clutch will not engage without voltage. If it doesn't engage, the compressor will not turn.
low freon
It's either low on charge, has bad wiring, needs a new pressure switch or needs a new clutch.
could be a bad bearing on the air conditioner clutch assembly.
Gear? That is what a clutch does. The clutch assembly which consists of the clutch disc and the pressure plate that applies the pressure to engage the clutch. The clutch on the front of an air conditioner pump is magnetic and engages metal to metal without a clutch disc between them.
In a word; no. However, the A/C compressor's clutch relies on your car's battery to properly engage, so one could say there is "a relationship".
air conditorner doesnt blow cold air has freeon compressor doesnt kick on
On all cars, the air conditioner clutch is on the front of the air conditioner compressor. The clutch is a unit by itself, while it's mounted on the shaft which is part of the compressor. A belt drives the clutch, and the clutch (when engaged) drives the compressor. Clutches tend to be held on in odd ways, snap rings might be involved. Also a puller is usually needed. Don't head into this without checking the information for your specific car.
yes you can
I'm investigating this as well. I have a 2008 and have been told the air conditioner is only off when you have the vents on the floor only. Still checking this out.
you would need to add freon
There is no fuses for the air conditioning clutch, but there is a relay mounted on the passenger fender beside the fuel pump relay.
