My compressor would engage but there is not even a cool air coming through any of the vents.Also,when the compressor is OFF(engine on) still makes a very annoying squeaking sound as the clutch slips on and off.
What is your opinion - should I just get a new/rebuilt compressor and convert
the system to R134a or keep the original R12?
R12 is hard to find and very expensive too.

I would appreciate any inputs and info.
Thanks!
