Climate control fan not working
Late model Ph2 (CF3 engine) spider.
The fan stopped working today. I've checked fuse (number 14 in the fuse box) and had the motor out - it spins up with 12v across it.
Unfortunately my copy of the service manual does not include the circuit for climate control, only manual controls and the wires are different colours.
The fan is driven from two wires, one pink, one orange going through a blue connector. Pink is always live with a full 12v. The orange one changes according to the fan speed. I would have thought, with the fan speed on 4, this would be 0v in reference to earth but my voltmeter shows 10v with reference to earth. With the control at speed 0 this drops to around 6v. Seems backwards to me.
Any help appreciated!
