When you start driving the doors will automatically lock and it quit doing it about a week ago. Also, the roof button (which hasn't in a while) doesn't work. I was curious if this has happened to anybody and if they know how to fix it. May be a fuse... help! thanks in advance.

are you currently in a cold climate? certain sub zero ambient conditions can cause electronics not to functions properly.

one way to check the sunroof switch might be to try and open it with they key. Some cars will open the windows and sunroof if you turn the door key like you're unlocking it and then hold it there for a bit. My 2000 528 does this. If this opens the sunroof then you at least know the window works, then you can check the switch.

its normally around 40 degrees here, and i'm ment to say the TRUNK. my bad.
