CAMPAIGN: FRT. DOOR WINDOW BINDING AND/OR INOPERABLE
GENERAL MOTORS HAS DETERMINED THAT CERTAIN 1992 BUICK SKYLARK AND SKYLARK GS SEDAN AND PONTIAC GRAND AM SEDAN MODEL VEHICLES MAY EXHIBIT A CONDITION IN WHICH FRONT DOOR WINDOWS REQUIRE EXCESSIVE EFFORT TO RAISE AFTER BEING LOWERED, OR MAY BE COMPLETELY INOPERABLE. THIS CONDITION IS A RESULT OF SOME WINDOW REGULATOR ASSEMBLIES BEING INSTALLED INCORRECTLY AT THE VEHICLE ASSEMBLY PLANT. THE INNER PANEL CAM MAY HAVE BEEN INSTALLED BACKWARDS (180 DEGREES OUT OF POSITION) DUE TO AN ERROR IN MANUFACTURING AT THE WINDOW REGULATOR PLANT. WHEN THIS CONDITION OCCURS IN A VEHICLE, EXCESSIVE FORCE WILL BE REQUIRED TO RAISE THE WINDOW FROM OPEN TO CLOSED POSITION. THIS WILL BE MOST NOTICEABLE TO CUSTOMERS IN VEHICLES NOT EQUIPPED WITH POWER WINDOWS, BUT WILL EVENTUALLY LEAD TO DEFORMATION OF THE WINDOW REGULATOR. IF THIS CONDITION CONTINUES TO EXIST, CUSTOMERS MAY NOT BE ABLE TO RAISE THE FRONT DOOR WINDOW(S) TO CLOSED POSITION.
DEALER ACTION
TO CORRECT THIS CONDITION, DEALERS ARE TO INSPECT VEHICLES FOR CORRECT INSTALLATION OF THE WINDOW REGULATOR ASSEMBLIES, AND WHERE NECESSARY, REPLACE THE REGULATOR ASSEMBLIES.
VEHICLES INVOLVED
INVOLVED ARE CERTAIN 1992 BUICK SKYLARK AND SKYLARK GS SEDAN AND PONTIAC GRAND AM SEDAN MODELS BUILT WITHIN THE FOLLOWING VIN BREAKPOINTS:
PLANT YEAR MODEL PLANT CODE FROM THROUGH
1992 BUICK SKYLARK LANSING "C" NC600081 NC602381 1992 PONTIAC GRAND AM LANSING "C" NC200024 NC201972 "M" NM000006 NM000142
INVOLVED VEHICLES HAVE BEEN IDENTIFIED BY VEHICLE IDENTIFICATION NUMBER COMPUTER LISTINGS. COMPUTER LISTINGS CONTAINING THE COMPLETE VEHICLE IDENTIFICATION NUMBER, ARE FURNISHED TO INVOLVED DEALERS WITH THE CAMPAIGN BULLETIN.
OWNER NOTIFICATION
A DCS MESSAGE HAS BEEN SENT TO ALL BUICK AND PONTIAC DEALERS WITH INSTRUCTIONS TO HOLD ALL SUSPECT VEHICLES UNTIL THE CAMPAIGN SERVICE PROCEDURE HAS BEEN PERFORMED. ALL SUSPECT VEHICLES MUST BE HELD AT DEALERS AND REPAIRED BEFORE OWNERS TAKE POSSESSION OF THESE VEHICLES. COMPLETION OF THIS CAMPAIGN LIFTS HOLD ON SECOND POPULATION OF VIN'S IN THE DCS MESSAGE. THERE WILL BE NO OWNER NOTIFICATION FROM BUICK OR PONTIAC.
DEALER CAMPAIGN RESPONSIBILITY
IN THE UNLIKELY EVENT A VEHICLE HAS BEEN SOLD PRIOR TO RECEIVING THE DCS MESSAGE, THE OWNER SHOULD BE CONTACTED BY THE DEALER AND ARRANGMENTS MADE TO MAKE THE REQUIRED CORRECTION ACCORDING TO INSTRUCTIONS CONTAINED IN THIS BULLETIN.
