babymog...thanks for the reply.
That was the first thing I checked for was an on/off switch that I might have tripped when cleaning the windshield. But there is no switch anywhere on the mirror.
There are two sun light sensors....one in the bottom right corner of the mirror and on the back side of the mirror housing facing forward. I am suspecting one or both of those little 1/4" round sensors are bad. They are the same sensors on my outdoor solar lights and security lights around my house....and they don't last more than a few years exposed to hot and cold temps.

I'll have to pull it apart and put an ohm/volt meter to it.

Thanks again!
Cheers
