Honda Ridgeline Door Lock Actuator Replacement

My passenger side door lock died a slow death and finally stopped working, after picking up the service manual on eBay I decided to give repairing the lock myself a go.  This procedure is for the passenger side door, the driver side will be similar but not identical because of the lock cylinder.

Parts Required:

  • Passenger side door lock actuator 72115-SDA-A01
  • Driver side door lock actuator 72155-SDA-A01

Tools Required:

  • Trim pad remover (I picked one up at Sears for $8)
  • Phillips screwdriver
  • Flat head screwdriver
  • 10mm socket
  • 8mm socket

Ridgeline Door Lock 004 Pull back the inner handle and push in on the notch at the bottom, this will pop out the cover.

Ridgeline Door Lock 008 Remove the 3 screws behind the inner door handle.
Ridgeline Door Lock 032 Now remove the 8 trim pad clips with the trim pad remover tool.  Once all 8 pads are removed start with the back of door panel and pull upward, be sure not to use too much force.

The door panel should come off without too much effort, once it does unplug the door switch harness and courtesy light plug.
  Raise window glass fully and pull away the white plastic sheet starting with the end by the lock, only pull it back halfway.
