One thing that I really don't have a good troubleshooting/repair understanding of is auto A/C systems. The BWB had the a/c light flashing on the control panel .... I reset that and it fired right up. It was cool out (highs 50's/ low 60's) when I did that .... air seemed cool.
Today it's in the 80's, so I turned on the A/C. It worked good letting the truck run in the drive. I headed out, dropped Stewie at school and headed to the bank. As I was leaving the school, the A/c started blowing hot air. I got home and popped the hood, the compressor was not engaged. If I jump the connector at the pressure switch, the compressor will run but the A/C still blows hot.
Is something plugged up?
I have access to a dual gauge a/c manifold set, but what am I looking for when I hook it up?
How do I tell if the system has already been converted to R134?
Thanks guys ...
