Just had my power door lock switches on both doors and the controls to adjust my side mirrors stop working on my 2000 Silverado 1500 Extended Cab 3 door 5.3L V8 if all that matters. Doors still lock and unlock with the key fob and when accelerating over 20mph/removing the key. I assume both stopped working at the same time but it is possible the mirrors stopped working before the locks since I don't frequently adjust my mirrors. Haven't made any changes recently, locks were working earlier today.
