So here is the latest email I received from an aftermarket OEMGM parts supplier that I’ve been going back-and-forth with. ——————- Part number 84041609 is listed as a passenger side mirror, for 2015 2500, or 3500 applications manufactured with option code DQS. Part number 84228892 is listed as a passenger side mirror, for 2015 2500, or 3500 applications manufactured with option codes AFV, DQS, without option K40. Per VIN 1GC1KWEG1FF191571 supplied the truck was manufactured with power folding mirrors, option code DL3. I apologize GM does not list a power folding towing mirror after the vehicle is manufactured. We understand you want to add parts, options or accessories to your vehicle that were not original equipment on your vehicle when it was manufactured. In order to supply you with the part numbers desired, we will require the VIN FROM a vehicle that was manufactured with the items in question. (**NOT YOUR VEHICLES VIN**) Without this VIN we will not be able to determine the correct part number you need. Many of our customers have found a vehicle either at their local General Motors dealer or know someone that has vehicle that is equipped with the parts desired and have supplied us the VIN number from that vehicle. We will help you in any way possible but we need a good VIN for the parts you want The licensed GM parts catalog does not provide the part numbers necessary to add an option to a vehicle that was not originally manufactured with that option. If the items are ordered, please note that they are special order, nonreturnable parts since the vehicle was not manufactured with these items. Please keep in mind the parts will not be warrantied by us, or GM, since the parts in question are not original equipment parts on the VIN supplied. Vehicle programming, or modification maybe required to add an option. Please remember we do not have any way of telling if a part from another vehicle will fit your vehicle properly without modification to the part or to your vehicle. Please research parts that are not original equipment on your vehicle to make sure they will fit your vehicle. No one wants to be stuck with parts that don't fit due to bad information.
