I can't get the AC control to work for AC or heat. Fuse is ok in block but I can't seem to find a troubleshooting schematic in the service manual on how to check to narrow down the problem. Suggestions?

 

Well, you can start by telling us exactly what doesn't work. Fan? Vacuum controls? Temp selector? What?

Also, is it Comfortron or manual A/C?

 

Got it fixed. Down side is the manual doesn't have a trouble line to follow in the manual AC but does in the comfortron. Ended up being the hold relay on the right fender was bad. Blower now works and AC compressor activates.
