The Air Conditioner condenser fan on my son's S80 always runs (the fan with the radiator fan). It runs regardless of whether or not the Air is on. Any ideas where to look to fix this?
Thanks

Have you checked the relay(s)? if you pull the relay out the two small spades are the signal/return and the large spades are the power to the device. You should be able to measure resistance and see if it changes when you apply 12v. PS, not sure if the relay/switch is built into the fan unit so there may not be a relay to play with - google around for a wiring diagram etc to start.
