[s-cars] A/C compressor and charge issue

[Pasqualoni, James E]

Fairly sure the 93 is R12.  Also, if it were too low on refrigerant, the
compressor would shut down via the low pressure switch.

The A/C compressor on my '93 makes a slight knocking noise most of the
time, and I can tell the charge is low, because the air coming out isn't
very cold.  I try to keep it turned off most of the time to prevent
further damage, assuming it's already not 100%.

I didn't see a sticker under the hood, but I assume these are 134a cars.
I thought I might try to put in an oil charge and maybe a can of
refrigerant and see if that helps before I take it to the stealer, but I
wanted to poll you guys first.  I see a new compressor isn't cheap...

Thanks,
Mark
