I am looking for the exact same thing. I want to get the standard mirrors with heat, power adjustment, turn signal and puddle light to replace my factory tow mirrors with those same features on my 2019 ram. Did you have any luck finding mirrors? if so where?
I initially ordered them from a libertymoparparts.com, but most of the parts were on backorder for 'greater than 90 days'. I ended up finding all of the below parts on ebay by searching for model numbers (each item from a different seller) and everything is here 6 days after ordering. I've got everything in hand now except for the passanger mirror but that should be here later this afternoon. You might need to be patient to find what you need - and you might even get lucky and find a nice pair of mirrors to order in a single auction.
I've not installed these yet so can't 100% confirm, but I am expecting my setup to be flat black, power fold, power adjustable, heated, autodim. I don't have BSM on my truck, but the mirrors have the icon them. Here are the part numbers I ordered and the prices I paid (shipping included) on ebay:
68262252AC - Front Door Switch And Bezel - $75.02
68424179AC - Door Module, Left Front Door - $87.19
68424178AC - Door Module, Right Front Door - $79.31
68462771AB - Outside Rear-View Mirror, Left - $227.91
68276502AH - Outside Rear-View Mirror, Right - $288.50
Total: $757.93 (which is within $10 of my order from LibertyMopar)
I am planning to program these mirrors with AlfaODB using an old android phone (app costs $50) and paring it up with an ODBLINK MX+ tool I got from amazon ($140) as well as a security bypass from amazon (AUGOCOM FCA 12+8 Universal Adapter Cable Adapter - $21.99).
This brings the
grand total to $969.92.
I followed some advice I saw from kjn86 post #9 on this thread:
