Door locks won't open

Hi, this is Bo, an auto expert on RepairPal's Car Genius team! It sounds like your Cadillac STS might be dealing with a glitch in the driver’s side door module. This module controls the locks and windows, so when it’s on the fritz, weird things like this happen. Since the front doors and windows are acting up, but the back ones are fine, it’s likely an electrical issue tied to that module. A professional can check if a reset or replacement is needed, but in the meantime, you might need to go manual with the key and the old-fashioned window crank. If you need any further advice or if you'd like any help finding a trusted RepairPal shop in your area, please feel free to call us at 877-913-1554!
