my cooling fan has stopped working. when i bought the car the fan was not working 2.0 petrol, i then cleaned all the pins on the relays still not working , then checked the fan itself and it was seized up . so i then replaced it and it worked fine then , unfortunately it stopped working the other day, i have checked the relays again they ok and the fan works ok if you power it direct so no problem with that , just wondering if their could be another fix someone could help me out with ,,
