Question about 1995 GMC Sonoma
You may have a few different problems including a defective pressure switch
when you added the "correct R-134" did you also add oil?
replacing that many parts requires additional oil
Therefore, you may not have enough "pressure"
do you have a/c gauges?
did you evac the system for at least an hour after replacing the parts?
