Am I reading correctly that the servo on the driver's door is just not
locking and unlocking the door?

Can you hear the servo moving when you hit the button?  If so, take a look
at the edge of the door and make sure the rived holding the mount in place
has not sheared.

That happened on the passenger front door of my '97.  Cost me about a
quarter to put a screw in place after taking the whole thing apart.  That
was a couple hour job.

Good luck,

Dave

The door lock itself was worn out, the thing you put the key in. The
door would not unlock with the key or the keyless as the lock assembly
will move with all functions. My brain told me it was an easy fix, ha,
should have left it alone and had it done right the first time. I broke
the door lock motor in removal and that made the cost go higher.
As for the Land Rover my son had one, $60,000 + for junk. Less than one
year old and all the power steering hoses, metal ends, and A/C hoses
were rusty under the hood. GPS quit and the thing leaked water all over.
He had to give it away as resale is so poor, good for the dealer but
poor for you at sale time. I pull a bass boat and have had very little
problems with my Explorer. Have over 127,000 miles and no major
problems. Heater blend door and key lock are the only big ticket items I
had to replace. Rear brakes are original but shocks are RS 5000's.
