I discovered today the I don't have cold A/C anymore (worked fine last summer). I can hear/feel the compressor short cyclying (about 5-10 seconds). I firmly believe I have lost R-12 (pressure) just slightly (an ounce or two) below specs. The last time I tried to charge my system it wouldn't take any freon and ended up wasting a can of liquid gold (R-12).

I have one can of R-12 Oil Charge that I'm hoping will bring my system up to spec enough to keep the compressor engaged.

My questions are:

Before I blow up my system and waste another can of R-12 and that is which side do I hook up to, to charge the system and where is it located on this vehicle?

Will I need to jump the low pressure switch to charge the system or should the system recover rather quickly?

Just in case I decide to measure the freon level in my system, what should the psi be on the low and high sides?
