rear door lock/latch mechanism? 87 4kq

[Luke Rickert]

Of all the possible topics, I thought something connected to broken door handles would be covered widely in the archives, anyway here goes.

The problem (on an 87 4kq)is with the rear passenger side door which has never worked right  (two years and 4 handles)

Today I pulled the latch mechanism off the door, soaked it in solvent and then re-lubed it, pulled the door panel out and checked out all the guts I could find. As far as I can tell everything is properly lubed and this been the least used door, should not be worn out?

Anyway it still has the same problems where after the door is locked and unlocked, by the power locks, it may or may not open from either side. You can pull the inside handle and hear a click, but sometimes the latch does not release. I had to pull the panel off with the door closed (not fun) and manually work the lever for the outside handle to get the door open because the outside handle was jammed. Another strange thing is that sometimes when you use the inner handle, the latch only partially releases and the lock knob comes down a bit. In these cases if you hold the lock knob up while working the inner handle the door will open fine. Once the door has been opened and not re-locked it generally works OK. I can’t find any thing that is adjustable in the system other than bending linkages to change their lengths. I suppose there could still be something sticking in the latch mechanism, should I find another one or is there something else I can try? I don’t usually haul that many people in the car, but it is still nice to have all four of your doors functional. Since the front doors never give me trouble maybe I should get some seats that lean forward out of a coupe.

thanks

Luke
