Jetta 2 litre fan switches on when i start the car
I have 2006 2litre jetta comfortline and when I start the car the fan goes on, is this normal?
So I assume you mean the radiator fan, and no that is not normal. Possible shorted fan switch or a circuit cross connect in the ran circuits wiring, has be rewired to run fan when key is turned on.
So in this case what must I do? I am bit confused about what you are saying about the circuits.
If you have any doubts then take it too a shop you trust, cooling fans failures is something you don't want to mess with as it can create serious engine problems. Your right this is something a novice would have problems with trying too fix themselves.
