Anyone know how to turn on the heated exterior windows?i really need to start learning about my car. I just got a 2007 audi a4 and i have no clue what i am doing

 

What is a heated exterior window? Are you talking about the heated mirrors?

 

Welcome to Audis.... you just bought a 2007 A4, that's barely a year old, so where is the owners manual ? ( I didn't know they had " heated exterior windows ", not sure what that means.
If you don't have an owner's manual, Benley Pub. has good owner's/service manuals, use Google.

 

I assume you mean heated door mirrors. If so, they either a) turn on when the rear defroster is turned on, or b) turn on when the ambient temperature drops below a certain point (that's how they are set up on my 99).
