2007 Mercedes S600 US version
I have an S600 of the year 2007. The four doors locks are unsynchronized. When I lock the doors, the front left, front right, and rear left doors are locked, but rear right is unlocked. When I unlock the doors, the front left, front right, and rear left doors are unlocked, but the rear right door is locked. Any person here had a similar problem. I assume the mechanical part is OK, but it is eight a setting problem or electric parts fail. Please help if you had solved a similar problem.
