Hi everyone I have 52 plate cooper s
Looking for help on the dreaded stage 1 fan and p/s fan not working

So all fuses are ok relays are ok p/s fan not seized

I have put 12v straight to high speed fan comes on no probs but
When I put 12v through low speed the relay at resistor just clicks and no fan

Any ideas where to go next apart from scrapping the car ?

the low speed is usually the resistor has gone so no low speed,not sure about the p/s fan ,aint they temp controlled?

Hi I have already changed resistor
You think it might be faulty
I have already changed resistor
Only a week ago
no sure on yours but on mine it has 3 wires (2003 r50)to the fan/controller,one wire is neg from the fan,one wire is full speed to the fan and the other wire goes through the resistor so if you have full speed then the fan is ok,so its either a faulty resistor or a break in the wire to it.can you use a multimeter set on resistance and see if you have a circuit?
