WINDSCREEN DE-MISTER BLOWER FANS NOT WORKING

Post by RS6C5AVANT81 » Fri Dec 23, 2022 2:10 pm

Hi All,
My windscreen de-mister blower fans have stopped working today even though they were working fine earlier on today when i first got in the car.
All blower control buttons on Centre console are illuminated and work.
But when you put the fan on with the buttons the fan isn't coming on / kicking in at all.
Any ideas on what this could be ? I've checked the fuses they all seem to be ok!
Has anyone experienced this issue before ?
Any advice will be greatly appreciated ?
Thanks
James

Most likely is the fan. Have you checked to see if you're getting voltage to it?

Resister is easy enough to change but not sure if when that fails it gives a constant rather than variable speed. Remove the glove box and you will see it on the ducting.
