Edit: So , I found the problem. It was acutally the electronic climate control box (the whole box in the dash board). Turns out the connection wasnt very good, and it had acutally toasted the connection a bit. (You can smell the flux and rosin scent on the connector. ) Cleaned it up a bit, squeezed liberal di-electric grease, and back in it went. Worked all day today. /forums/images/graemlins/thumb.gif Sure enough, the problems with my truck are popping up. There is no AC. Thought it was just the freon level- Tried to add Freon. Compressor doesnt kick in. the electronic AC control (in the 92-94 years) the amber "AC" symbol just flashes. Any ideas?
