My friend has asked me to have a look at his car, the cooling fan is not kicking in, other than checking the wiring,fuses etc first is there any common problems with these that anybody can shed any light on before i take a look?
The fan should also run at a slow speed when the AC is turned on, so if it does run, the problem may be in the sender side, if it does not run, the problem may be on the fan side. - If the AC works!
