Either folding mirror switch folds the pass side

[Tahoedav]

Title says it 2011 ZTZ which ever switch I push the pas side folds in. the driver side folds in by hand easily. I do not get why either side I push folds the same mirror/ Any ideas?

The power folding feature always folds both mirrors at the same time (the side selector only applies to mirror adjustments), so something is preventing the drivers side mirror from working. Chances are it's a stripped gear in the mechanism. Can you hear the motor run on that mirror when you try to power fold them?
