What if my stock mirrors are the GM power fold (DL3) mirrors?
For the 2003 – 2006 and 2007 Classic GM trucks with the stock power fold mirrors the install is a little different than our other models. This applies to models 6141 and 6141T. You simply take the stock mirrors off, put ours on in the same spot, and plug them in. Your GM dealer then needs to reprogram your door module from a DL3 mirror code to a DPF (power extend/retract) mirror code. At that point, your truck’s mirror programming is just like it would have been had it come from the factory with power extending mirrors. You do not need to install any wires or switches. The switch and wires that were doing the power fold will instead do the power extend/retract.
