I'm not sure that this is a DIY job. My Haynes manual has no information about actually repairing a compressor. It does, however, go into length about changing out the entire compressor. You should have the system depressurized by a certified AC tech. There are environmental considerations here. Haynes says that when you replace the compressor, to be sure that it A. has oil already in it or B. drain the oil from the old compressor into a graduated container. Add the exact same amount of new oil into the new compressor. When replacing the compressor, you'll also have to replace the accumulator/drier and the expansion (orifice) tube.
low freon, bad pressure switch, bad compressor clutch.
We need more info here. How do you tell if the clutch has "WHAT" in a Pontiac Sunfire?
The labor to replace a clutch on a 1996 Pontiac Sunfire can range from $670 to $850, depending on where you go. This does not include the cost of the clutch itself, which is roughly $800.
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.
Buy a Manual. ;)

The neutral safety switch is found under the clutch pedal on a Pontiac Sunfire. Crawl under the cars steering column to see and reach the unit.
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
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?
there is a puller you can borrow it from your local autozone
you have to remove the tranny and clutch! 4-6 hours depending on who and where you get it done and the tools they have most people charge about $70/$80/hr
Could be the clutch is gone. If that is the problem, you can have just the clutch changed, but don't wait too long. If it is the bearing, then have to change the compressor. When it is running, you will see the clutch wobble. The clutch can be changed with the compressor on the car. There is room.
