Door mechanism problems...HELP!!
'79 Suburban, front doors (non-power)...sometimes when you lock it you cannot get the lock to come back up no matter if you use the key or manually try to pull it up. Then, miraculously, I got it to come up with the key after jiggling the key...seemed like something was stuck. Another problem is sometimes the push knob on the outside (to open the door) will just push in freely and not engage anything, like it's just flopping around....then after opening the door a time or two (from the inside), it will begin engaging again and open the door. Anyone have these kinds of problems?? It's driving me nuts!! Any thoughts or cures will be appreciated!!

sounds like one of the rods that work the latches is bent or something. Take the panel off and have a look

I agree with Adam.
One of the beautiful things about our trucks is how easily the door panels can be removed (compared to modern plastic/concealed fastener stuff). The linkages inside the door are also pretty straight forward. Once you pull the panels, diagnosing the problem should be pretty easy. Have fun. ![]() ![]() ![]() |

on my old truck (76) the outside door handle was jamming half in and half out.the door handle seemed like you said it would go in and not engage because the inners were engaged. it would make it so ya couldnt move anything. What i did was to get a can of gumoput and spray the lock and handle as well as i could to clean off all the dirt and stuff in it that would impede the lock and the guts of the door handle from working then i sprayed it good with some WD40 and a little white grease to lube it and thus far its been fine. ya get alot of dirt in the handle etc and the things gum up and quit working

basically just had the same/similar probs on my 76 4x4. Just pull the panels for the best access and I used a can of white lithium grease. I greased everything. All rod pivot points, all springs, the channels for the window regulator, lock mechanisms, handle springs, u name it then spray it. If not immediately then within a day or two's normal use you should find that no more binding will occur and everything will work well. My main problem was if u mashed the open button on the door handle before unlocking it then it put it in an unlockable state and you had to push and release the button several time to get it to free up.

In regards to the door handle not working the same thing happend to my brothers car (85' Pontiac Parsienne) except in reverse the inside handle wouldn't work, I forget if the rod had actually fallen off or if it was just bent but it wasn't much of a job to fix it.
