Is there a dedicated fuse for the power side mirrors on the 2003 Trailblazer? I can't find anything in the fuse panel for mirrors. Can't move them and the defrost doesn't seem to work either. Mainly I'm concerned about getting them to move. Everything else on the door panel works power windows and locks. I suspect it could be the switch as it's gotten wet a few times over the years. Why I can't find a fuse is a mystery to me.
