I have the autodimming rear view mirror with compass. at some point in time part of the top half of the letters stopped lighting up and the bottom half was dim. I don't know when this occured, I just noticed it a month or two ago. Today I was working under the hood and had the battery disconnedted for about 2 hours. When took the car for a drive after I was done I noticed the compass was lit up like it should be.
WHAT COULD HAVE CAUSED IT TO FIX ITSELF??
