General Motors has decided that a defect which relates to motor vehicle safety exists in certain 1997 Chevrolet Blazer and Suburban; GMC Jimmy and Suburban; 1998 Chevrolet C/K Extended Cab Pickup, Astro Van, and Suburban; and GMC Sierra Extended Cab Pickup, Safari Van, and Suburban vehicles equipped with electric outside rearview mirrors. Under certain conditions, some of these vehicles may develop a short circuit in the electric outside rearview mirror switch. If this were to happen, it could result in an inoperative switch, heat damage to the driver's door and/or ignition of components in the driver's door and a subsequent vehicle fire without prior warning.

Involved vehicles have been identified by Vehicle Identification Number. Computer listings containing the complete Vehicle Identification Number, customer name and address data have been prepared, and are being furnished to involved dealers with the recall bulletin.
