Sounds like the freon is gone. You'll have to test the system for leaks. Either the compressor is bad or one of the lines/connections is bad.

no it will not run well, u need special parts to run this fuel, without them the fuel system will quite literly disolve also cold starts are very much affected, in wintwer the car weill not start without gas being used to prime it..

I think you are talking about a cv shaft. Does this sound only come when you turn the steering wheel far one way and in motion. If so they it is most likely a cv shaft. The cv shaft usually runs about $50-75 and labor will probably be another $75.

USE A U CLAMP & PUT IT IN THE CALIPER &THE TO THE OUTSIDE OF CALIPER. IT LOOKS LIKE VISE GRIPS. HAVE A FRIEND PUSH ON THE BRAKES. WHEN CALIPER COMES OUT, SQUEEZE U CLAMP SNUG, REPEAT UNTIL U THINK IT,S FREED UP. BLEED THAT CYLINDER ALSO INCASE IT,S FULL OF AIR, WHICH MAYBE CAUSING UR PROBLEM. CHARLIE

The compressor pulley requires a special puller and installer to service it. These kits cost about $30. Most parts houses carry this tool. Many have a tool rental program for such a tool.

You will have to inquire at your local parts house as to if a belt is offered that is less the AC option. My guess is that your car was never available without this option.

It is the starter solenoid that you have found bad...

The wiring and their connectors on your type of car are gold-tipped, so as be corrosion free, and are able to make all lights come on, even in coldest weather.
This should not be happening to your car at this time, however. Below 30F is way too small to affect those lights.
Perhaps moisture had built up in the system during the previous hot summer. Or some ground wires are contaminating, or even rusting where they are bolted to?
You could check up a few items here, such as the ground wires. Clean them out and dry. Inspect the fuse/relay boxes to ensure they are clean and dry. Spray some electrical contact cleaner.on them if they show signs of contamination or elecrical deposits.
Replace the battery terminals if they are old, and worn.
