My 2011 Hyundai Santa Fe rear door lock wouldn't lock or unlock from the car's remote control or from the driver's side panel. I don't know if this is a common problem with 2011 Hyundai Santa Fes.
I've tried to troubleshoot by opening up the rear door panels completely twice and reached the actuator. And it seems each time I opened up the door, the lock worked. Then I reassemble the panel the door wouldn't lock again. I don't know what else to try. Is this a common problem with my vehicle model? What do I need to do next? Thank you!
