Well they didn't work all winter which pissed me off, is it a hard fix? It's not the fuse because the rear window defroster works fine.

 

I'm showing 2 fuses. The 20 amp one in the PDC which does the rear window and feeds a 10amp fuse in the fuse block, fuse "A" for the heated mirrors.

Check it out.

 

I will thanks.

 

Could that be a fuse isssue? I am thinking not after reading this thread. What's the fix and is it expensive?

 

on my truck one mirror stopped working. the heating element in the mirror are prone to burning out. check for power going to the element or check for resistance at the element. that will tell you if there is a break in the heating wires in the mirror. i do beleive you can change out just the glass on our trucks.

 

I didn't even know heated mirrors were an option on Dakotas lol.
