Hi guys, i have a B5 model A4, the wing mirror is acting funny. I have a retractable ones in my audi.
When turn the mirror **** to retract, i have hear the passenger side motor running, it retracts, but driver side is not working at all. Secondly, when turning back to normal, the passenger side not returning to normal, driver side stays as un-retract.

What is the problem?
Where shall i check?
Which fuse is relating to this?
