Inside couresty light coming on while driving

[finall]

Has anyone had this problem, and how did you solve it?

2006 H2.

Once in a while the passenger front door will turn ON the courtesy light while driving. Just on this one door. All other interior lights stay off. Noticed it at night, but might do it during the day also, when it would not be noticeable.

This is really freaky, especially since all other lights are off. Pop, it just comes on and goes off by itself. Is there a short somewhere that completes the circuit?

WTF? How could THIS possibly happen, and where do I start looking for a solution? Do I need an exorcist?

Anyone have the answer?
