I have 2000 Chevy Blazer 4.3 V6 with A/C problems.
This model has the Electronic Climate Control and when I bought it the heat would not go off and the compressor would not start and the vent controls would not work> I replaced the the Electronic Climate Control. All the controls worked as normal except the compressor was not getting voltage and not coming on. So as my friend and I were trying to figure out why the compressor would not engage. there were 3 or 4 pops under the dash and the controls began to blink. I pulled the dash and moved the actuator the light stopped blinking but now i'm back to heat only. What could the problem be. I'm out of ideas with this fancy control that don't work
