I’m trying to retrofit my 2020 Laramie that didn’t have an auto-dimming passenger side mirror with one that does auto-dim. My driver side mirror already does have auto-dimming. So, I purchased a new mirror with the auto-dim feature and I’ve installed it on the truck. Plugged the connectors in to where the previous non-dimming mirror was connected. No success getting the mirror to actually dim, though. All other functions work (folding, heating, blind-spot, etc.). Wondering if there is a code I need to update. Does anyone know what the code may be or if there is another remedy I’m missing? Thanks for the help.
