I think that this may have been addressed some time ago, but at the time I didn't realize that I had a problem.

My front doors seem to lock just as they should, but neither the sliding side door nor the rear hatch will lock when the front door locks are activated by the key.

I opened up the switch connection on the passenger-side pillar.  There are 4 connections, but mine only had wires leading to three:  the top, the top-middle, and the bottom connections.  There appeared to be only these three wires in the harness leading to the switch.

Before I discovered this, I had been installing wiring in that pillar to run an extra lamp, and to run a permanently mounted fan.  My concern is that in the process I might have somehow pulled the connecting wire off of that lower-middle connection, and that it is now somehow stuck up in the pillar, somewhere.

However, this would not readily explain why the rear hatch automatic locking would not be working.

Any thoughts or suggestions would be appreciated.
