Deck lid warning light staying on
 

My wife's '00 Intrepid has an intermittent problem with the dash warning light for the deck lid coming on and staying on.

I pulled the trim from the inside of the deck lid and wiggled the cabling while watching the dash light. At a certain point, the light turns itself off, but then it's supposed to be on since the lid is open, leading me to believe that there is a short in the wiring.

As a temporary fix, I unhooked the harness from the lock assembly. While it disabled the remote opener on the dash and the key fob, it didn't turn off the light.

Where do I start diagnosing this? Can't pull a fuse since it shares a circuit with some other lights. Thanks.
