WATERLEAK AT DOOR GLASS AND QUARTER WINDOW AREA

SUBJECT: WATERLEAK AT DOOR GLASS AND QUARTER WINDOW AREA (DIAGNOSTIC/SERVICE PROCEDURE)

MODELS: 1988-94 CHEVROLET CAVALIER 1988-94 PONTIAC SUNBIRD (ABOVE VEHICLES ARE CONVERTIBLE MODELS ONLY)

CAUTION:

TO HELP AVOID INJURY TO YOU OR OTHERS WHEN RAISING OR LOWERING THE CONVERTIBLE TOP, KEEP YOUR HANDS AWAY FROM ANY HINGES AND LINKAGE AND CLOSE ALL LATCHING HANDLES.

THIS BULLETIN IS BEING ISSUED TO HELP IDENTIFY POTENTIAL AREAS OF WATERLEAKS AT: A-PILLAR WEATHERSTRIP TO FRONT RAIL WEATHERSTRIP, FRONT RAIL WEATHERSTRIP TO CENTER RAIL WEATHERSTRIP AND CENTER RAIL WEATHERSTRIP TO REAR RAIL WEATHERSTRIP.

BEFORE PERFORMING ANY REPAIR PROCEDURES, VERIFY WITH OWNER THAT PROPER CONVERTIBLE TOP OPERATING PROCEDURES AND CONDITIONS HAVE BEEN OBSERVED AS FOLLOWS:

- NEVER RAISE OR LOWER THE TOP WHILE THE CAR IS MOVING. THE WIND COULD GET UNDER IT AND CAUSE DAMAGE.

- IF AUTOMATIC CAR WASHES ARE USED, IT IS RECOMMENDED THAT A SOFT CLOTH CAR WASH BE USED AND THE VEHICLE CLIMATE CONTROL SYSTEM SHOULD BE SET TO "VENT" AND THE FAN BE SET AT ITS HIGHEST SPEED. THIS WILL PREVENT THE HIGH PRESSURE WATER FROM ENTERING AROUND THE CONVERTIBLE TOP.

- DO NOT TRY TO LOWER OR RAISE THE CONVERTIBLE TOP IF YOUR VEHICLE IS OUT IN COLD WEATHER, 41 DEGREES FAHRENHEIT (5 DEGREES CELSIUS) OR BELOW. THE COLD CAN CAUSE CRACKS AND OTHER DAMAGE TO THE CONVERTIBLE TOP AS IT IS BEING LOWERED OR RAISED.

- DO NOT LOWER THE CONVERTIBLE TOP IF IT IS DAMP OR WET. AFTER THE CONVERTIBLE TOP IS DOWN, THE TRAPPED WATER CAN CAUSE STAINS, MILDEW AND DAMAGE TO THE INSIDE OF THE VEHICLE. BE SURE TO DRY OFF THE CONVERTIBLE TOP BEFORE YOU LOWER IT.

- MAKE SURE THERE IS NOTHING IN THE CONVERTIBLE TOP STORAGE WELL (THE AREA BEHIND THE REAR SEAT WHERE THE CONVERTIBLE TOP WILL GO) OR UNDER THE WELL IN THE TRUNK. EVEN A SMALL ITEM COULD DAMAGE THE REAR WINDOW OR CONVERTIBLE TOP WHEN IT IS LOWERED.

- THE CONVERTIBLE TOP IS NOT DESIGNED TO CARRY WEIGHT. NEVER LET ANYONE SIT ON THE CONVERTIBLE TOP, AND DO NOT PUT ANYTHING ON TOP OF IT WHEN IT IS UP OR DOWN, OR IT COULD BE DAMAGED.

- ALL SIDE WINDOWS MUST BE PARTIALLY LOWERED BEFORE LOWERING OR RAISING CONVERTIBLE TOP TO PREVENT WEATHERSTRIP AND SEAL DAMAGE OR DISPLACEMENT WHICH COULD RESULT IN WATER AND/OR WIND LEAKS.

GATHERING DETAILED INFORMATION FROM THE VEHICLE OWNER IS A VALUABLE TOOL IN LOCATING AND REPAIRING WATER LEAKS. IT MAY BE NECESSARY TO ASK LEADING QUESTIONS TO THE LOCATION AND CONDITIONS WHEN WATER LEAKS OCCUR. SOME HELPFUL QUESTIONS MAY BE ASKED AS FOLLOWS:

1. WHAT AREA OF THE VEHICLE DOES WATER APPEAR? 2. DOES WATER LEAK OCCUR WHEN IT RAINS? 3. DOES WATER LEAK OCCUR WHEN VEHICLE IS WASHED? 4. IS VEHICLE WASHED IN AN AUTOMATIC CAR WASH OR IS IT WASHED BY HAND? 5. HAVE SEALS OR WEATHERSTRIPS BEEN SERVICED PREVIOUSLY? 6. HAVE DOOR OR QUARTER WINDOWS BEEN SERVICED PREVIOUSLY? 7. HAS VEHICLE BEEN IN A COLLISION AT ANY TIME?

AS AN AID IN DIAGNOSING WATERLEAKS, THE FOLLOWING VIDEO SHOULD BE REVIEWED: "PONTIAC TECH TRACK SUNBIRD CONVERTIBLE WINDNOISE AND WATER LEAK DIAGNOSIS AND ALIGNMENT".

THE VEHICLE SHOULD BE VISUALLY INSPECTED AND WATERTESTED WITH WATER TEST STANDS AS DESCRIBED IN SECTION 10-1 OF THE APPROPRIATE SERVICE MANUAL.

CHECK AND ADJUST QUARTER GLASS ALIGNMENT IF NECESSARY. REFER TO SECTION 10-7 OF THE APPROPRIATE SERVICE MANUAL.

CHECK AND ADJUST DOOR GLASS TO QUARTER GLASS ALIGNMENT IF NECESSARY. REFER TO SECTIONS 10-6 AND 10-7 OF THE APPROPRIATE SERVICE MANUAL.

CHECK AND ADJUST CONVERTIBLE TOP ALIGNMENT IF NECESSARY. REFER TO SECTION 10-9 OF THE APPROPRIATE SERVICE MANUAL.
