The rear passenger power door lock stopped working on my 91 accord-all others work fine. Still works by hand but will not work with the power controls. Tried lubing with silicone spray but this didn't seem to help. My thoughts are it is the actuator but don't know for sure. What is the appoximate cost of this part and getting it replaced. Not sure I want to tackle this myself as I heard it may be a PITA. Any other thoughts on how to fix this are welcome.

 

The PITA part is removing the door panel and putting it back together when you are done. Other than that, I think it is pretty straightforward.
Sounds like it could be an actuator to me too.

 

take off the door panel and pull the actuator. Plug it into where it plugs in, and press the power door lock button. If the white thing at the top moves, try it again but stop it with your finger. If its fairly powerful, door lock actuator is fine. If it puts out a small amount of force or grinds, actuator is busted. If the white piece doesnt move at all, and the actuator makes NO noise/vibration/activity at all, it could be a number of things.

 

I have the same problem all of my door locks are messed up like seriously, they open and close when they feel like it. Not like jus open, but if i try to open it either one open or two but not all four, same thing for closing. And if all four work then all four wont open, as i said all messed up.

 

it's a pain in the ***. it's bolted to the door latch which has to be removed to replace it. if you want to tackle it let me know, i'll post the info on how to do it all.

taking em out is fairily easy, but its a major pita bread to put them back in.
