Help - Radiator fan does not work - overheating!!

[PaulSmith]

I haven't managed to do all the checks yet, but on first inspection found out that the radiator fan fuse was burnt out  :eek  so replaced it yesterday on the way home from work.


The fan still didn't start up though. I'm getting a multimeter this weekend and will check the relays and hook up a battery to the fan to see if it still works as there is no debris to stop it spinning.


Also, I read somewhere online that HID lights are problematic for the radiator fan circuit - something to do with the ballast charging up causes a power surge that will burn out the radiator fuse. Has anyone else had problems with this?

Have you tried going faster?

More seriously, I don't know what you read or where, but why the foc would the headlights (HID or otherwise) have anything to do with the fan circuit?
