Door Lock Actuators

[tf95ZR1]

My driver's side door lock actuator grew gremlins.
I think.
It click-click-clicks while driving and the "door open"
light on the dash flashes on/off. I know it's not just
the door switch. I've dealt with that before and just
the dash light flashes, no clicking.
Anyway I plan to remove the door panel and look for
any shorts or loose connections.

I even bought a replacement actuator just in case.
I read the FSM re: actuator replacement. It says
you have to drill out some rivets to remove the old
actuator then rivet in the new one. Correct? WHY WOULD
THEY RIVET IN A REPLACEABLE PART? I'm surprised
they didn't locate it under the plenum.

Anybody ever have this problem? Fix?

TIA
