Sorry if it's been addressed somewhere else, but my laptop does not agree with this forum and it runs super slow, so searches are taking forever.
2005 Yukon with 96k miles. AC worked perfect last Fall. Got warmer and tried to use it a couple of weeks ago and no cold air. AC compressor not cycling on, so I bought a AC recharge kit. Showed no pressure when I initially hooked it up. Used the entire container and then the compressor started cycling but still no cold air.
Then, I noticed that even with the AC off, the fan doesn't blow until it's turned to the highest setting. Seems like the unit isn't responding.
I remember something similar happened last year when I disconnected the battery, the heater controls stopped working, so I had to disconnect the battery a couple of times and it seemed to reset itself.
That's not working this time.
So, to sum it up, I can have the fan control turned to 1 through 4 and no air is being blown through the vents. Turn it to 5 and it blows strong. I'm assuming this means that the control module is bad, correct?
