I have a 1995 chevy c1500 4.3 v6 with only a whopping 128,000 miles. The AC doesnt work. When I first purchased Susan the AC would kick on but due to a leek she wouldnt blow cold air. After fixing the leek, pulling a good vacume and pumping her back up with some 134A, the AC wont even kick on anymore when I press the AC button and turn the temp knob all the way on cold. I suspect that the AC button on the hvac control system probably went out considering it was wanting to kick on just fine before. Im in no rush considering its getting cold out but just wanted to see what you thought about it. The heat works just fine and the controls work fine for the heat.
I had this problem when I needed to put more refrigerant. The guy I took it to put way too much in and when I took it somewhere else all they had to do was bleed the system to the correct level and it worked like new. If that doesn't help hopefully Scotty can! https://www.youtube.com/watch?v=Vi7Xri91860
Might be the AC compressor
