Thread: Replacing passenger door lock actuator

I have a 2 door GP and when I hit the switch or use the key fob to lock the doors, only the driver side will lock. The passenger side makes the sound you hear when you lock the doors, so it's trying to lock but getting stuck somewhere or the mechanism to lock the door is failing. If I manually flip it to lock, the door is locked just fine and will also unlock like normal.

I've sprayed the rods with WD40 but that didn't change anything. What could the issue be? Do the lock mechanisms in the door actually go bad?

This isn't a big deal but if it's something I can fix easily then I'd like to fix it.


Edit: Pictures are below.

Could be the door actuators/ lock motor or the knob that you push/ pull is binding on the door panel. I have replaced the lock motor in a fox stang with the same problems, but yet in a GP. My driver lock knob likes to bind on the door panel when I unlock it, not when I lock it though...so I have just dealt with it.

Then most likely a bad lock motor, if going by process of elimination.

they aren't to bad, you take the inside door skin off, and take the actuator off. its close to the key lock. if you cant see it work the lock, you'll feel it or see it moving. has a linkage bar from it to the lock. just be careful with any of them plastic rings you may have in the linkage. they get old and brittle, and break.

It takes all of 5 minutes to get the door panel off and check it out. Dive in homie!

heres a list of ebay sales for this, looks like the lock its self comes out, and you change it all.

either way it looks like those 3 screws on the outside by the door latch hold the whole lock plate in. after its out you should be able to work on it.

Glad you are tackling this, I have done this on other cars, never a GP though. Seeing how you do it will help me out cause my driver lock is getting slower by the day. So I will be following after you LOL.
