Why is my Audi Q7 mirrors not working?

If Your mirrors are not moving manually on Your AudiQ7 then it's going to be an issue where the rubber has become damaged. You're going to want to look at it to inspect it for damage. If instead Your issue is with the power mirrors then it's likely going to be a problem with the electrical system. You're going to want to first try replacing the fuse that goes to the mirrors. If that doesn't fix it then it's possible that the switch that controls the mirrors has become faulty. These issues with the electrical system will often need a professional to look at them.
