The power folding mirrors on the driver’s side and passenger’s side of the vehicle (Fig. 10) may appear to operate at different speeds on some 2019-2023 Silverado 1500, Sierra 1500; 2020-2023 Silverado 2500HD/3500HD and Sierra 2500HD/3500HD models.

If the power folding mirrors appear to not be in sync, it’s important to note that even though the power folding mechanism for the outside mirrors runs at the same speed on both sides of the vehicle, the passenger-side mirror will compete the folding maneuver faster since it has a shorter folding distance.
The power folding mirrors, which are controlled by the Driver Front Side Door Window Control Switch, will fold or unfold depending on the current state. The Front Side Door Window Control Switch controls the fold/unfold motors through bi-directional control circuits.
Do not replace the mirrors for a power folding speed concern. This is a normal operating characteristic of the power folding mirrors and the system is functioning as designed. The operating speed of the power folding mirrors should be shared with customers.
