I have a 2003 Chevy Trailblazer. My A/C has been reclaimed and is empty. I have a vacuum pump and the proper R-134a Gauge tree. The only problem is that I lack the experience in doing this. How dow I properly charge my system? I tried this last month and over charged it. I need to know if I am suppose to conduct a vacuum on both the high and low side at the same time and what pressures I am looking for.
Thank you for your help.
Dave

Most evacuates/reclaimers for a/c 134A is connected to the low side only, and pulls only 30psi.
