I'm having the same problem with my passenger door and also the same problem differentiating what the correct part number is! Can anyone kindly advise at all?
The jp-carparts link above has 2 variations of #23:
23
72155-S5P-A11
Add inquiry
ACTUATOR ASSY.,DOOR LOCK
23
72155-S6A-J11
Add inquiry
ACTUATOR ASSY.,L.DOOR LOCK
I assumed that the bottom variation, 72155-S6A-J11, was the correct part, again assuming 'L' stood for left-hand side. The prices for both are also different which adds to the confusion.
Most places online only appear to stock the the driver's side, the part number for which matches #5 on the list:
5
72115-S6A-J01
Add inquiry
ACTUATOR ASSY.,DOOR LOCK
Any help on what the correct passenger side actuator part number is would be much appreciated, if anyone knows for definite! Thanks.
Update - Tegiwa have confirmed via Honda that 72155-S6A-J11 is the DC5 passenger side part. 72155-S5P-A11 apparently comes up as the equivalent part for a Civic.
