Mr. Jim

Went out this morning and started my truck with power folding trailering mirrors. Passenger mirror did not stop in the correct position but continue to travel fully forward. The power mirror will retract into the park position when switch is pushed, but when I try to operate them in the normal position they swing through and the mirror actually point towards the outside of the truck. The passenger mirror will NOT park in the normal user position. I have an appointment to take the truck in and let the local dealership look at it, but wondered if it may be just a simple reset I can do. 2020 AT4 GMC Sierra 2500 diesel w/ power folding trailering mirrors
