Got the aircon regassed today, and I cannot get the condenser fans to work.
The fans themselves are fine, if I operate relay 13, or 14 the each of the fans kicks in on full speed, if I operate relay 18, they both come on at half speed, so the wiring from the relays themselves is all ok and doing what it should, it just seems that the ecm is not asking for the fans to run when the aircon is switched on.
Also, does anyone know exactly how the Dual Pressure switch (trinary switch) works? The explanation in the workshop manual makes no sense whatsoever. It basically seems to say that the switch has 3 modes, open circuit, closed circuit, or 'shorted'. Not sure how the 'shorted' mode differs from closed circuit.
I also had a problem with the compressor clutch not cutting in, but managed to solve that by removing the shim from the spindle, to reduce the clutch plate gap. Any comments whether I can consider that a permanent repair or not?
