I'm usually pretty good at searching for answers, but this one has me a little stumped.

My passenger side mirror controls are stuck in the towing, or vertical, orientation. With the mirror flipped down, the controls are rotated as if the mirror were still flipped up.

When putting the truck in reverse, the mirror tilts out, instead of down. I've tried flipping it up and down, and making sure the housing is clean, but no joy. I had to change my presets, otherwise it would get messed up every time I started the truck.

Does anyone know if there's a sensor or magnet in the mirror to detect when it's vertical vs horizontal? Or any luck resetting the mirror?

I have a 2013 RAM 2500 Cummins, no mods that would affect the mirror AFAIK. Just steps, air bags, cabin air filter.

My truck does have the DEF deleted, so it must have some sort of programming, but it's pretty minimal.

I still have the EGR parts in the engine bay.

Any help would be greatly appreciated!
