I was reading Quicktips in the March 2010 Motor Home edition, and this tip deals with installing a Dome Light Switch with Harness Kit from a company called Quadratec. The company supplies mostly Jeep parts but this might be the solution for having to pull the circuit breaker on the Malibu. The tip in the magazine explains it much better, or go to www.quadratec.com and search for Dome Light Switch.
