Thumbs down Cooling fan

Toady I checked out a strange noise from the front of the X3. With the engine running I noticed that the electric cooling fan is not running unless the Air Con is switched on.
1. Is there a possible cause for this strange nocking sound? 2.0d RSA model
2. Is it normal for the electric fan not to be running with engine idling? Heat gauge stays within normal range.

Thanks for the advice.

Blessings

Your fan shouldnt stay running at all times so it perfectly normal. When you kick your ac on the fan cuts on to to blow through the condenser as part of you ac system. The cooling fan should only click on when the engine reaches a particular temp, but if it never clicks on then you would have issues but with it not over heating at idle then your good. That means its working. You might just not be waiting long enough to see it click on.

The knocking sound I only hear in mine wheN the ac or heat is going. There is a thread here some where that explains it but I cant remember exactly what it was.

Talking

Electric cooling fan now fixed. Pulled out fuse, cleaned contacts with sandpaper and replaced it. Fan now running again. Thank you for the advice.

Discovered that electric socket in luggage compartment not working. Uses same fuse as cigarette lighter. Both cigarette lighters working. Any suggestions will be welcomed.

Hi

My joy was short lived with electric radiator fan. Local mac send me to auto electrician who could not diagnose reason for electric radiator fan not kicking in. Local Mac said that if 1 radiator hose stays cool while the other 1 is hot it indicates problems with thermostat. Both mine are hot at normal temperature.

Auto electrician was afraid to test green wire running to fan with red one. he claims that it usually blows computer box.

Blessings.

Start with a multimeter. Is there 12V from the vehicle chassis to the centre of the cig lighter? Is the GND resistance low from the chassis of the vehicle to the chassis of the cig lighter?
