Hi,
I may not be understanding exactly what the problem is with the door latch either.
Being confusing to myself, is a trait I can do well.
So, I will ask,Is it the lock for the key or the latch component itself that you think has seized?
Art’s pictures of a rusty motor case in the housing shouldn’t keep you from physically moving the knob up and down.
The key cylinder should be able to lift it all up or down.
It would not be safe to design the system any other way.
Since this is the passenger side door, the latch lever, for the actual locking mechanism, doesn’t get assistance from the solenoid motor unless the drivers side key or knob is used.
The drivers side of the car uses a central relay to operate all the doors simultaneously.
What can happen is the outside handle “lifting linkage” gets out of adjustment and will not quite pop open the door latch completely. What ever a human touches can be breaking first.
So consequently, it won’t rotate the claw and gets hung up into a “limbo” mode and cannot rotate backwards to reset.
Just enough, to screw it all up.
The inside handle is not so critical as the PULL
direction IS different and simpler.
It is not subject to being snatched on.
The Outside handles get to pull on the whole door just before it opens!
A person may lift it by using a thumb to assist lifting the handle but that can present a wear pattern on the paint finish above the handle. It’s also a sign of things going south.
Once a person feels that happening they go to using the thumbs more elsewhere.
Gripped the chrome harder and yanking.
The pot metal joints, of the handle itself, is going to give out prematurely.
All of this happens so slowly but then suddenly, it’s in there or broke!
There is a specification called out in the manuals for it.
The outside handle is allowed just so much free play, as it has to have a full stroking length to work right.
I suggested earlier, to work both the inside and outside handles at the same time can get it to go far enough to open the latch most of the time.
It’s a heavy warning to heed!
Of course, you have to have, the window down to work both sides or have the door open to observe or assist the latch lever claw.
This probably stems from the latch mechanism itself is really dirty or gummy or in the case of electric unlocked they are dragging excessively.
I think Art has zeroed in with his pictures that the gearing should move the armature slide or vice versa otherwise.
So it his idea or mine is the outside handle adjustment or a plain out right gummed up latch.
It hard for me to imagine the passenger side latch being worn out at any years of age, but I haven’t seen everything that can happen .
You might study the latch and strikes holding tightness.
With that statement I will add that the Chevy Camaros had major problems with the door strike adjustments .
The hinges were too lightweight (cheap) to hold out or on to such a long door heavy door with its electric motors and glass length.
Sometime the looks of a car comes with a price to pay.
Probably explains why I look the way I do!
I must owe something?
