# SERVICE MAN. UPDATE-SEC.8A-69 HEATED WINDSHIELD CIRCUIT

The wire colors shown in the 1989 and 1990 Service Information Manual, Section 8A-69, for the heated windshield connector to power module and control module are incorrect. Update your Service Information Manuals with the following information:

The red wire from the heated windshield connects to the BLK/WHT wire from the power module which is the negative lead circuit 364.

The BLK lead connects to the RED/WHT wire from the power module which is the positive lead from the power module circuit 365.

The YEL wire connects to the LT BLU wire from the control module.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
