Greetings All:
1984 Vette, 16000 original miles.
AC compressor not kicking in, believe needs charging.
Am I correct compressor won’t kick in if low on coolant?
Secondly, fill on High Side?? And is high side line the one on that silver can like canister?
Lastly, fill with car running and AC on Max, correct?
My Quick Fill kit has a gage on hose that tells when fill is in the green area. As Always, Thanks in advance for your help.
Willow👍😊

Always charge on the low side, ac running. Should be evacuated first, see if it holds vacuum.

I would suggest that you get someone who understands AC better. Those high side pressures can get up to 400 PSI and can be downright dangerous.

The kits sold over the counter only connect to the low side (suction) side for R134a. For an old R12 system, you are going to need to do a retrofit. It is not the end of the world but someone with AC skills and a recovery machine will go a long way.

If you were close to Birmingham AL I'd help you.

If it's an old R12 system I would just bite the bullet and have it re-charged with R12 after they check it for leaks. The R12 works so much better.

I must respectfully disagree. The cost of R12 is total nonsense. I've retrofit a few and had great results. The car has an electric fan and a large condenser.

Wait until you see what R12 costs versus the R134a.
