At the end of last summer, my powered rear view functions all of a sudden stopped working. Parked in Philadelphia, and then when I started it back up, no temp read or compass functions worked. Also, there is no way to dim the mirror at night. I checked the fuse and it seemed to be okay ( i believe its on a 10A). Oh, btw I've got a 2003 XE. Anyone have any quick fixes or suggestions for me w/o buying an entirely new rear view mirror?
