Help! Rear View Mirror Day night function quit working

[mdebry]

The electrochromic mirror has quit working, no green power light. All other lights work, reading lights, vanity mirror lights, hood light all work which also come off the 2 fuses, so power is avail. Any one know of some fairly easy trouble shooting before I relent to a repair shop. I have a 2004 C5 coupe

Not trying to be antagonistic or sarcastic, but did you try the power button on the mirror (see p. 2-38 of your Owner's Manual)? It's possible you or another driver just inadvertently turned it off...? :confused

Yes I did check the switch, however problem is solved. Turned out to be the fuse located in the inside fuse box. I had read that 2 fuses supply power to mirror, and that they also power underhood light, vanity mirrors, reading lights and a few other items. Since everything else worked I assumed it was not a fuse.
