The loss of stop lamps and rear hazard lamps could fail to warn a following driver that the vehicle is braking and/or is stopped and could lead to a vehicle crash.
On certain minivans, the multifunction switch may develop an open circuit condition in the stop lamp or hazard lamp circuit that results in the stop lamps and hazard lamps being inoperative.
Dealers will replace the hazard warning flasher switch and apply special grease to the contacts at the time of installation of the module free of charge. The repair would be used in vehicles in which the hazard slider button is still movable. If a vehicle has a hazard slider button that is not movable (frozen), the entire multifunction switch will be replaced. The recall began on April 13, 2005. Owners may contact Chevrolet at 1-800-630-2438 or GMC at 1-866-996-9463.
