Fuse?
 

My wife just called on her way to work this morning: Garage door opener/closer on mirroe not working; directionals not working; may be other things, tail lights/headlights/brakelights all work. Is this a fuse? If so where is the fuse located and wat ampereage.

Most likely a fuse, open the hood, driver side towards the rear there is a rectangle plastic box with a clip holding it on, there will be a guide on the lid showing the number fuse and amp type, locate blown fuse and replace with same color fuse, there should be some spare fuses there also,

Look in the owners manual my 01 has a fuse box under the rear seat, and another on the drivers side of the dash under a panel.

3 fuse boxes on that car. Can't know for sure unless you check them.
