Windshield replacement affect rear-view dimming?

The split in the rear hatch glass casts a shadow directly over the small square light sensor of the mirror. It was bad enough on my 2016 Prius I was glad to have a manual mirror on my '22 Prime XLE.

 

Have you tried covering the sensor on the back of the mirror with your finger, in broad daylight? That test should trigger the mirror to dim. If it doesn’t (and of course is “On”), then the mirror is probably malfunctioning.

Seems you have already confirmed there is power and that is good. Perhaps try pulling the fuse for a few mins and reinsert to “reboot” the mirror and see if it makes a difference?

Not much else to think of at this point, maybe need to see a dealer or specialist. I can’t think of any reason a windshield replacement should affect this unless it is somehow resulting in unnatural light on the rear sensor.

 

I was thinking a wire to the mirror got strained or pulled loose during the install process.

 

Pop open the plastic cover with (see FITCAMX dash camera installation video for instructions). I’d post a link, but I’m not at home right now. As Trollbait suggests it is likely just a loose connection.

Home now, here's a link:

 

Can u share how much is the windshield replacement?
