Door lock knobs won't push down
 

Hi folks - I have a recently purchased 65 pony car. I noticed that I am not able to push the door lock knobs down to lock the doors when exiting the car. The only way to drive the knobs down is by using a key when the door is closed. Does this sound right? If not, any insights on what the problem might be?

After 50+ years everything the locking mechanism probably needs a good going over. Pull off the door panel and see what you have going on.

Ok, so it sounds like I should normally be able to push down the knob manually. Yup, need dive deeper. BTW, I appreciate the warning in your posts.

Oh yeah, they need to go up and down with only minimal resistance.
