Audi Q7 2014 100200 miles
I can find the air pump relay for the front of the car. My fan motor is working in the back and I think "secondary" means the one at the rear? Fan in the back is working but not in the front when I turn everything on. I have owned the car for several years and know I am not doing anything wrong so there must be something wrong with the car. I have attached a picture of the secondary air pump relay.
