I have a 2003 Range Rover vogue and the heater doesn’t work for about 20 mins not even the fan works after a short period it starts working ???

If it is in auto mode - the system will wait for the coolant temp to rise before it actuates the fan - else all it will do is blow cold air into the cabin!

If it is doing it when you manually select fan speed, then I would be looking at the Final Stage Resistor as this is what controls fan speed.

Thanks for that in the manual mode the fan just will not work at all but seems to be OK when car is warmed up, so the fan will not work when engine cold but is fine when temp is normal?? Is it still the final resistor and where do I find it please.
