I bought a used 2015 GMC 1500 SLT and it came with the towing mirrors on it. I want to know which mirrors I got. DPS or DQN? How can I tell? The sales guy said they have power folding but the wiring wouldn’t allow to power the motor on the towing mirrors, even though it had it before. I can manually fold them in, so is that still possible with motorized? Sent from my iPhone using Tapatalk
