My truck came with towing mirrors but I recently smacked one and need to replace (cracked housing). I called a local dealer and they gave me the part number based off of the VIN, 84691670, GREAT! Dealer wants $650 for ONE mirror (not heated, not auto fold) way to much. So, I go to GM Parts Direct, enter VIN, and they don't even list my mirror. None of the GM sites list it by VIN. Direct search part number and it shows up. Go to dealer's site, put in make/model/year and get part 23372182. Similar, but not the same. However, the set of TWO list at $750. This same mirror comes up on the GM Parts sites as well with make/model/year (cheaper) and only $80 more than my part and I get a set, but says a new harness is required. This set is at least heated (which is not) and I'm figuring the new harness is what's taking this into consideration.
So, the question is, does anyone know if this is actually a replacement? I'm kind of thinking that in true corporate America fashion, they decided to make a newer mirror backwards compatible with a different harness and save on making the older mirror?
