Here's an interesting problem I have - the driver's door lock will unlock with the remote and the button on the door, but it won't lock with the
remote or the door button. This was an intermittent problem where sometimes it would lock, other times in wouldn't. Now it seems to have stopped locking
all together. I took the the door panel off and checked out the locking mechanism to make sure nothing was loose, but it all looked fine. Any ideas?
