The rear view mirror in my 08 F250 started freaking out last week. It dims then lightens up, dims then lightens up, dims then lightens up..... etc, etc. I can't get it to stop! lol Is there a sensor I can take a look at and/or replace or am I looking at a new mirror? Is the sensor built into the mirror itself?

Kind of a cheesy question but I was hoping that someone either had this problem before or knows what I can look at - test - replace to get it back to normal.

Thanks!

 

Mine did that a few weeks after I got my truck for a couple days then just up and quit. Try turning it off for a day or 2. I believe that's what I did

 

I've got 2 of them if you need a replacement

Usually the silvering just gives out. Never seen one freak out

 

And how the heck do you turn it on or off? I didn't know you could!

 

unplug it. simple connector at the back of the mirror

 

Yeah...that'll do it!

 

Mine has a power button lol

 

Thanks for the help guys! I ended up just unplugging the sensor from the back and it stays un-dimmed now. At least I can see out of it and it's not driving me insane changing colors the whole time I'm driving!
