2019 Midnight Tow Mirror glass adjustment

Larry Brigden · April 15, 2021

This is an unusual question. I have a 2019 Midnight Edition 2500HD in Australia. Just replaced stock mirrors for aftermarket tow mirrors. Problem is that the LHS mirror cannot be adjusted to see down the LHS of the truck when sitting in the RHS front seat, which is the driver's seat in the RHD version sold in Australia. I bought the mirrors off eBay from the US.

Does anybody know if the mirror can be opened up and modified to give it more adjustment of the glass so that I can see down the LHS of the truck? Probably no one in the US has ever had to do that modification, so I realize that this is a long shot.

A question back at you....Did you LHS mirror tilt BEFORE you added tow mirrors? If it did, there's probably a wire change that can be done. You would need to research that or talk to the mfg of the mirrors. IF the LHS didn't auto tilt tilt before, you may need a recoding. Also, have you tried turning that option on in the information center? Just my thought.

Yes, the LHS (and the RHS) mirror was able to be adjusted before adding the tow mirrors. The problem is not that the mirrors will not adjust at all, whereas once they did. The problem is that the LHS mirror does not adjust enough to see down the LHS of the truck.

I do not remember turning that option on in the information center.

Seller of the mirrors informs me that the glass in those mirrors cannot be removed. So, apparently I will not be able to get behind the glass to modify the mechanism.

Thought this would work but does not:

You just adjust the mirror by the switch on the door to about the centre position. Then get out and tilt the mirror by hand in toward the vehicle. Then get back in the truck and use the switch to tilt the mirror further in.

There appears to be just is not enough space for the mirror to move further in on its near side.
