I have a new to me 89 RS that has factory AC. The blower motor works, the system appears to have charge, but AC does not work as the compressor does not engage.
When I started looking into it, the wiring seems to be the reason. The low pressure switch is wired to ground, and there is some sort of aftermarket relay situation wired into I believe the AC wiring. I intend to reset to factory wiring, but I have an issue:
I have attached the schematic for reference. It appears that there should be a LT Green wire coming from the AC controls in the car, to the low pressure switch. Where might I find this wire?
The wire then leaves the low pressure switch, and continues on to C105. C105 appears to be on the firewall, near the blower motor box. That sound correct?
