Heated Mirror Fuse

[jessed1]

My Driver's side heated mirror is not working (yeah, that time of year already). Anyone know which fuse powers this mirror? I can't find in my book or online.

Thanks,

The heated mirror circuit originates at the door module, so there is no fuse specifically for the heated mirror. Fuse F45 (30 amp) in the interior fuse box is for the power to the driver door module, but if that fuse is bad, then none of the mirror features, windows, or locks would function on the driver door.
If it is only the driver mirror heat that isn’t working, then it’s either the mirror heating element, or an issue with the driver door module itself. You could use a scan tool capable of reading faults in the door module to point you to the exact issue.

You could also take off the mirror glass and possibly ohm out the heater grid.

Shoot, since there is no separate fuse, guess I will need to have the dealer look at it. I ran it for 15 mins this morning. The passenger side was warm to the touch and the driver's side was cool. I may try to get a FLIR camera before I take it in to show the dealer.

Hmm, could do that but it's under warranty. Dealer *should* be able to correct.

my passenger side mirror nukes the fog off in less then a minute my driver side take

Only blind spot part of the mirror glass is really heated, this part is defrosted very quick, for the remaining glass it's takes much longer. I have a filling, that's on my '14 RaM defrosting was much quicker, but I may be wrong.

Turns out it was the mirror - of course it has taken 7 months for the dealer to get a replacement. It gets installed on Saturday, figure November before I really get to see if the new one is better.

Brand new 2024 similar issue. I can see the heated circle almost immediately on my passenger side but it takes maybe 5 minutes before driver side mirror starts to defrost. Weird.

MY ‘22 is the same way. Never had an issue with my 4th gen. Both mirrors would nuke the frost quickly. After reading a few of these posts with similar issues, it doesn’t bother me as much now that I know it’s not just me.

Kap, thanks for the pictures and instructions, I have my passenger side mirror not working after I got too close to another object and slapped my mirror against the glass, Nothing broke but the heater does not work on that side. I am hoping a wire came off, if that is not it I may just ignore it.
Thanks.

My new driver's side mirror (replaced under warranty) actually works properly. No clue why the original one barely functioned.
