Re: a/c
I just finished getting the A/C (both front and rear)working in my 1990 Suburban. I replaced the compressor, condenser, receiver/drier, the expansion tube. I did not replace the rear evap though. Once I got the system together, i put the vacuum pump on it and left it running for a couple hours to get all the moisture out of the system. I then left a vacuum on the system for a day and checked it to make sure there were no leaks. Then I filled it with a little of 4 lbs of R134A and now the A/C blows out sub 40 degree air out of the front and back vents.
