This is about my 92 k2500- with the electronic style climate control stuff. I already posted in the IFS section, but its hot in florida!!! help!!! 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?
