I noticed today that the only lock that was responding to the power locks (either key fob or switches) was the driver door. Front passenger and both rears were non-responsive. I thought that it might be a ground or fuse problem and that the driver door might be on a separate circuit to minimize the chance that all four would become inoperable at the same time.

I checked the fuse box, "Maxi Fuse" 40 and 41 are labeled "Driver Door Node" and "Passenger Door Node", respectively, not sure what that means, but pulling the fuses didn't affect the locks at all, driver door still worked, others didn't.

I then noticed that "Mini Fuse" 46 and 47 are labeled "Passenger Door" and "Driver Door" respectively. I pulled both, fuses were good. I reinstalled the fuses and all four door locks began working. I thought I heard a single chime when I reinstalled the fuses. Did I reset something by pulling the fuses?

 

Possible that it did reset the lock module. BUT I would sooner believe the fuses remove and reinstall cleaned up contacts that fuse slides into.

 

Same issue as on 12/11/2018 with only driver side door lock and window responding. Other windows wouldn't go down, locks wouldn't engage, passenger side mirror wouldn't adjust. Removed and resinstalled mini-fuse 46, "Passenger Door", everything worked after reinstalling the fuse.
