Im in the same boat..

Did you get the running lights and turn signals to work? If so how Thanks

Dealer just called and said even with the replacement harness the truck itself does not have the pins into the BCM from the truck. They ordered Driver side 84622371 Passenger side 84622372 Their HAS to be a way to get directional and markers to work ?

Received this Email stating Harness in stock. My truck is currently at the dealer getting Tow Mirrors & wheels installed as part of our deal. The dealer ordered New Harnesses and had them in about a week, I will let everyone know what does and doesn't work. Stock mirrors had Heat and power adjust NEW PRAGUE CHEV (NEW PRAGUE, MN) (952) 758-4488 REYNOLDS PONT CAD GMC BUICK (ORANGE, VA) (540) 672-3700 These two businesses are showing to have those parts in stock.

No

I bought the harness and the dealer is telling me the adjustable glass and heat work but, no lights or did they not change the harness out ? my truck came with heat and adjust but, like I said I bought the wiring harnesses ? Thanks

Try GM 84469521

Truck is a week old and Fog lights dont work, just trying to get them up and running before appointment

Can you provide Programming instructions?

I'm new this this and have some questions Did your original mirrors have Heat and power adjust ? You stated "Power adjustment and heat worked right away" my factory mirrors are power adjust only, I want the tow mirrors to have heat, power adjust at a minimum. The directional and running lights wound be good as a bonus.

DO they have heat function and did you get the lights to work ?

OK..So Im new to this are we understanding the without the wiring harness that the turn signals work as plug and play? Thanks
