My driver side actuator started acting up, sometime locking and not locking and so. Ordered the part and replaced it today.
Not too bad. 1.5 hours. I'm a fairly advance mechanic on older cars (simpler I would say) with timing belt, engine removal/replace, clutch r/r and so on.
I would not pay no more than 1.5 hours of labor on this. Part was $35.00.
1. Driver side door actuator is 72155-S5P-A11. The passenger side is a different part number so make sure you don't mix it up.
2. A door panel tool that look like a bent 45 deg. angle screwdriver with a spatula end is needed to remove the door panel. There are five screws (3 hidden) that you need to remove for the door panel to be lifted up and away from the door.
3. Remove the 3 screws holding the door lock carefully: use a hammer and bang against the screwdriver to loosen the screws first.
4. You will need to remove a black 10 mm screw holding the glass rail
5. you don't have to take the entire assembly out but just enough to remove the actuator itself. You will need to remove a rod that goes into an opening of a part of the outside door handle. Lift a plastic lock out of the way and pull it out. this rod has a little nub to ensure it locks into the opening so it will resist a little.
6. removal of the actuator is via a small flat microscrewdriver inserted into the locking prongs on both sides of the actuator to release it from the bracket. You can see where the locking prongs go into when you look at the actuator itself.
7. be sure that the actuator driver (rectangular boss) lines up with the female counterpart.
