I sold my 2019 larame with auto dimming mirrors and got a 2021 limited with the power folding tow mirrors and immediately noticed because I drove home at night that the mirrors didn't auto dim. i looked closer and i see what looks like a light sensor under the mirror to cause it to dim but can't get it to dim. I am debating buying regular mirrors for $650 a set and swapping them for what is in my opinion a better mirror.
