[6pack] door adjustment

[John G. Sullivan]

During the winter, I find that the driver's door is hard to shut, that the
lock doesn't catch unless you slam the door. I have tried to clean and
lubricate the lock; however, that hasn't been too successful. How do you fix
this?

 

Also, I understand that by pushing the interior door lock forward, should
lock the door. Doesn't seem to be very effective on my car.

 

Any insight is appreciated.
