cheers steve ...................what area are you in?
Just studying the wiring diagram and there looks to be a few switches/components. Which one would you be referring to and where exactly would it be located?
1: Delay relay for air con (behind dash)
2: Switch for air conditioning (with thermostat)
3: Control solenoid, for compressor, air cond. 3.9A
I just put power to the wire going into the compressor and it clicks in.
I'm in Altona North :)
