So, recently my passenger side front door started doing this weird thing. Went to shut it as usual and it won't close all the way. It sits open about a half an inch. I saw that the door striker plate was all worn out, and all the plastic was cracked, so I replaced that hoping that would solve the problem. That didn't do anything. I'm thinking that there must be something out of adjustment with the actual locking mechanism in the door and I just don't know what to check or how to check it. Any suggestions are greatly appreciated.
