I've got a '97 TDi 110 with climate control and the interior fans have suddenly decided to stop working. The climate control panel works fine and I can hear the flaps moving when I change it from windscreen/interior etc. Sometimes the fans will start to work when I'm doing motorway speeds and they work perfectly from then on until I turn the car off again.
Any ideas what the issue could be? I'm looking to sell the car soon so would like to get this sorted asap if possible.
