No, problem only starts when engine is started. Approx. 30 seconds after engine is started fan comes on full power and will stay on sometimes for upto 10/15 minutes getting hotter as the engine warms up. On occasions fan will come on whilst car is being driven after travelling several miles and blows hot air into the car. Again it will stay on for several minutes before switching off again. An intermittent fault somewhere.
The car has air con not climate control. As I said in my original mail, you can not stop the fan by pressing any control or even switching the air con off.
Switching the fan control to off or adjusting the temp controls makes no difference. Even with the temp controls set at cold the fan blows hot air at full power into the car when it decides to come on !!.
Hope this info helps and that you can put forward a solution.
Is this a problem you cannot solve ???.
Chassis No of my car.
Trust this helps.
Thanks for info, will have this checked out and if necessary come back.
You were right, it was the fault of the resistor on the heater fan.
Replaced, now OK.
