mirror display dead

[axxense]

Hello all. I just had my windshield replaced - out of warranty.

Anyway, get in the truck and the inside rear view mirror heading/temp display is dead. I called the guy that replaced the windshield and he said they just unscrew with a torx - he didn't unplug it or start the truck or anything. Seems a it must be some occurrence of the windshield swap.

Can anyone give me some clues as to what to check or where to start? What the wiring should be or what I can check with a voltmeter? Is there some kind of reset trick? Also - which fuse protects it? I can't figure which one it is from the diagram - I did pop out the 'info' (don't remember the number of the fuse - it's in the lower right of the box) fuse and it is fine.

I figure I can pick up a working mirror cheap enough and replace it, but, I am thinking something is dorked and I should (with the help of you guys on the forum) be able to fix it. Also, I can't imagine the mirror display died so coincidentally and I am afraid if I buy a new mirror, it may be just fine, but, not work as the prob might lay in the wiring, the connector, a fuse, somewhere else.

Thanks.
