Side view mirror, switch not working?

I would start by checking the fuse # 37 in the under-hood fuse panel here is a guide to help and the mirror wiring diagrams so you can see how the system works.

If the fuse is okay chances are the switch has gone out here is how to change that out as well. Check out the images (below). Please let us know what happens.
