I have no power to the AC compressor. I have replaced the AC controller and I know the compressor is good. It works when I jumper from the battery to the compressor. It does not work if i jumper the low pressure switch. There is a plug along the firewall that has several wires on both sides and it looks ok. Im guessing the power that goes to the pressure switch is not there. I have checked the AC fuse and it is good. I dont think the 86 has a compressor relay. What color is the wire on the AC controller that runs to the compressor? I guess its possible i have a second bad controller. But not likely. Thank you in advance for any help here.
