Re: ABS Error when Aircon used

When air-con is switched on the radiatior fan automatically starts but switches off when the car reaches around 40 mph. So obviously the air-con UCH must a get a vehicle speed signal in order to control this aspect. This signal would be related to the ABS sensors either directly or via the ABS control unit, the dash or even possobly via the speed sensor wire going to the radio. In other words they have to be inter-related. Sorry I don't know the exact details of the system. I'm just throwing up a few ideas which may help trace the problem.

On the other hand I may be totally way off the mark.
