My driver side rear view mirror is having problems - auto dimming. It works sometime. Most of the time not. I did the test and it works. But at night it has problems (most of the time). The other mirrors work ok. I think I shorted something out when I was adding the smart tire monitor and power for the laptop. I've switched power location and even disconnect the devise. Still having problems.

Any suggestions would be helpful.
Thank
