What causes radio and side mirrors not to work on 2005 corolla?

There is a 15 Amp fuse in the engine bay in a fuse box located on the right near the battery which controls the radio and the clock (and possibly the mirrors). Open it up and look on the right column of the box. You will see a large 40 Amp fuse followed by smaller fuses above it. I cannot remember exactly which fuse it is, but it's a 15 Amp one. If memory serves me correctly, I believe there will be 3 sets of fuses. the lowest will be a 15A, followed by a 30A fuse and I can't remember which fuse is above that one, but the 15A fuse is the one to check.

If all else fails, check all the fuses in the engine bay and check the AM1 and AM2 fuses in the car located on the drivers side. There is no easy way to get to them, you will have to pop your head down by the gas and break pedal and look up into the dash. You will see a panel which is held in by clips. That is the fuse panel.
