I noticed the same problem on mine. Been working on it much of the day while reading posts. I thought I had the heater/blower aspect of it fixed and then it stopped working again. Very random. Blower works then does not.

Checked the fuse. Was corroded and cleaned it. It started working again... Then stopped. I checked the AC pressure and temp switches to determine if it was the CC unit. I pulled the Relay...Pounded on the bench a few times and put it back in. It worked! The compressor even started working again... Then stopped. I'm now getting seriously worried I'll have to replace or fix that CC unit that everyone says is so expensive..

I finally read a post about an ignition switch tumber... Jiggled the ignition switch while runining and low and behold everything works! Except one thing. My AC is not cold. The heater is killer now! But when you dial down the AC to max it just gets less warm. A little warmer that outside temp. Can't figure that one out. If the compressor works, it has to be charged...

Any ideas?
