INFORMATION ON CIRCUIT BREAKER OPENING IMPROPERLY

SUBJECT: CIRCUIT BREAKER OPENS WITH SIMULTANEOUS OPERATION OF POWER SEAT AND REAR WINDOW DEFOGGER

MODELS: 1992-93 PONTIAC BONNEVILLE

SOME OWNERS MAY EXPERIENCE A FAILURE WITH THEIR POWER SEATS AND REAR WINDOW DEFOGGER IF BOTH ARE OPERATED AT THE SAME TIME.

WHEN THE REAR WINDOW DEFOGGER IS TURNED ON AND THE POWER SEAT IS ADJUSTED (USUALLY TO ITS MAXIMUM FORWARD OR REARWARD POSITION), THE CURRENT RATING OF CIRCUIT BREAKER 4 IS EXCEEDED, CAUSING IT TO OPEN.

INFORM THE OWNER TO ADJUST THE SEAT FIRST, THEN OPERATE THE REAR WINDOW DEFOGGER.
