So i have a 1997 civic and for the first time I came across this problem.

Sometimes my passenger lock will lock when I press the manual lock button on the driver side door, but if i use my keyless entry alarm button to lock the doors, the passenger side doesn't seem to lock anymore. It was working just fine but now its developed some sort of problem. Im not to sure about, any help?

thanks in advance!

 

Test the passenger door lock actuator. It may be on the way out.

 

The metal rods that connects the power lock solenoid and lock you press is sliding on the joint/connecting point. Tighten the screw (red) so that the both rods are firmly joined.

 

i looked in the door panel and couldnt find the screw your talking about, are you sure thats for a 97 civic passenger door? I tried to find anything i could tighten but i found nothing.....

i dont no why it wont lock nothing looks broken and i just changed the window regulator a year ago

 

how do i test that "Actuator" ?

 

That's...that's not stock, at all. I don't know where you got that, Heisenberg, but you're way off base.

The window regulator is not the lock regulator. Different parts. It might just be on it's way out. As RonJ said, test it.
