When I lock my car I can only open the drivers door from te inside, how do I fix this? Don't no to much about doors, any Help would be welcome

 

You will have to remove the door panel and check the mechanisms which is kinduva pain. I had a similar issue on my Lincoln - needed WD-40 & some lithium grease. It's also possible something fell off or disconnected, but you will need to remove the door panel.

 

**** I hate messing with door panels, they never go back on the samw
