Recently, as I'm driving, the door alarm/indicator light keeps coming on saying that my driver's side door is open. The door is obviously closed, but the alarm, indicator light and interior lights continue to come on anyway. The driver's side window also drops down and won't go up, since it's reading that the door is open.

I pulled the negative battery cable to reset the ECU in case it was a bad connection. Now, the alarm goes ON when the door is closed and OFF when the door is open. And the interior lights are still coming on, too. If I slam the door really hard, the alarm will go off. But then if I hit a bump, it'll go back on, with the lights, indicator light and window drop. Next step is to lube the door switch...anyone have any other suggestions on what might be causing this?

 

There is a sensor for the door (believe its in the door) that needs replaced.
