Air Conditioning

I'm replacing the compressor on my '94 S-10 Blazer. I have a set of guages and a vacumm system. I will change the accumulator and want to flush the system. Change over to 134a. Just don't know just how to use all the tools.

Don't use 134a, use hotshot. It's a better freon.

They really only want licenced people to service air conditioning systems, and doing your own work might even be illegal where you live
