VEHICLE WINDNOISE/WATERLEAK (INFORMATIONAL)

SUBJECT: VEHICLE WINDNOISE/WATERLEAK

MODELS: 1993 CHEVROLET CAMARO 1993 PONTIAC FIREBIRD

THE INFORMATION IN THIS BULLETIN WILL IDENTIFY SOME POTENTIAL AREAS OF WINDNOISE OR WATERLEAKS.

AS AN AID IN DIAGNOSING WINDNOISE AND WATERLEAKS, THE FOLLOWING VIDEOS SHOULD BE REVIEWED. FOR PONTIAC - "TECH LINE VIDEO" AND CHEVROLET - "CHEVROLET PRO SERVICE NEWS".

THE AREAS IDENTIFIED WILL BE RELATED TO ONE OF THREE (3) AREAS OF THE VEHICLE.

- WEATHERSTRIPS TO BODY - GLASS OR APPLIQUE TO WEATHERSTRIPS - DOOR INNER PANEL AND COMPONENTS

EACH POTENTIAL ITEM WILL BE IDENTIFIED AS A WINDNOISE OR WATERLEAK ISSUE AND IF THE VEHICLE HAS A T-TOP OR FULL ROOF.

WINDNOISE

THE VEHICLE SHOULD BE ROAD TESTED TO DETERMINE THE LOCATION AND DEGREE OF WINDNOISE/TURBULENCE ON THE VEHICLE. IT IS IMPORTANT TO REMEMBER THAT WINDNOISE CAN BEST BE DESCRIBED AS AIR LEAKING FROM THE INSIDE OF THE VEHICLE OUTWARD WHILE TRAVELING AT HIGHWAY SPEEDS. TURBULENCE OR WINDRUSH IS BEST DESCRIBED AS AIR PASSING OVER AND AROUND BODY OPENINGS AND MOLDINGS.

PROPER DIAGNOSIS MAY BE MADE WITH A VARIETY OF TOOLS AND METHODS INCLUDING STETHOSCOPES, DUST GUNS, MASKING TAPE, SONIC INSTRUMENTS, VISUAL INSPECTIONS, DOLLAR BILL METHOD, ETC.

WATERLEAKS

THE VEHICLE SHOULD BE VISUALLY INSPECTED AND MAY BE WATERTESTED WITH WATERTEST STANDS (AS DESCRIBED IN SERVICE MANUALS), LOCALIZED WATERTEST METHODS, AIR PRESSURE/BUBBLE TESTING, ETC. IN THE CASE OF T-TOP EQUIPPED VEHICLES, THE GARNISH MOLDINGS ON THE WINDSHIELD PILLAR, REAR RECEIVER AND ROOF PANEL SHOULD BE REMOVED PRIOR TO WATERTESTING TO AID IN DIAGNOSIS.

IMPORTANT:

SERVICE REPLACEMENT WEATHERSTRIPS FOR T-TOP EQUIPPED VEHICLES MAY NOT HAVE SEALING MATERIAL INCLUDED UNDER THE MOLDED DETAIL AT THE FRONT ROOF GUTTER LOCATION. USE SEALING KIT P/N 10193836 WHEN INSTALLING THESE WEATHERSTRIPS, AND APPLY THE MATERIAL TO THE ROOF SHEET METAL AS INDICATED IN ITEM 1, VIEWS B AND C.

THE MATERIAL IN SEALING KIT P/N 10193836 IS A FOAM MATERIAL COVERED WITH BUTYL ADHESIVE. THIS KIT CONTAINS 54" OF MATERIAL AND IS USED TO MAKE REPAIRS TO SEVERAL LOCATIONS.

NOTE: THE LATEST T-TOP OPTION VEHICLES ARE EQUIPPED WITH AN "AWNING" BETWEEN THE T-TOP PANEL AND WEATHERSTRIP RETAINER. THE FOAM SEAL PAD ON THESE ASSEMBLIES IS ON THE "AWNING" SURFACE, NOT THE RETAINER SURFACE AS IN PAST MODELS.

THESE "AWNINGS" PROVIDE AN IMPROVED WEATHERSTRIP TO GLASS SEAL AND "BUTT JOINT" PERFORMANCE.

WHENEVER THESE AWNINGS OR WEATHERSTRIPS ARE REPLACED OR ADJUSTED, PLACE A PIECE OF MATERIAL FROM SEALING KIT P/N 10193836 UNDER BOTH ENDS OF THE WEATHERSTRIP TO RETAINER ON THE OUTBOARD EDGE TO THE END OF THE WEATHERSTRIP. THIS WILL AID IN SEALING THE WEATHERSTRIP TO THE RETAINER AND TO THE T-TOP GLASS.

EARLY MODEL VEHICLES MAY BE REWORKED WITH THESE PARTS TO IMPROVE WINDNOISE AND WATERLEAK PERFORMANCE. USE GM P/N 10254484 (RIGHT) AND 10254483 (LEFT).

- ALIGN THE CENTERING MARKS AND APPLY SHIELD TO THE BACK SIDE OF THE SPEAKER HOUSING AS SHOWN IN FIGURE 7-B (MAKE SURE TAPE SEALS TO ALL SURFACE CONTOURS).

- INSERT ART WORK (FIGURE 7-B) -

- PLACE THE SPEAKER AND HOUSING FACE DOWN, AND AT THE BACK OF THE HOUSING, FOLD THE SIDES OF THE SHIELD TOWARD THE CENTER, AND THE TOP OF THE SHIELD DOWNWARD. (SEE FIGURE 7-B)

- APPLY A LENGTH OF CLOTH BODY TAPE (DUCT TAPE) OVER THE FOLDED PORTIONS OF THE SHIELD TO MAINTAIN SHIELD SHAPE. (SEE FIGURE 7-B)

- CUT THE EXCESS SHIELD MATERIAL EVEN WITH THE BOTTOM OF THE SPEAKER TO PROVIDE ACCESS TO CONNECT THE WIRING CONNECTOR FOR THE SPEAKER.

- THE FINISHED SHIELD SHOULD HAVE (APPROXIMATELY) A 1" OPENING AT THE BOTTOM FOR WIRING CONNECTOR INSTALLATION AND VENTING.

NOTE: ON SPEAKERS WITH AMPLIFIERS, CLIP THE WIRING CONNECTOR TO THE SIDE OF THE SPEAKER HOUSING, NEAR ITS ORIGINAL LOCATION.

B. USING SEAL KIT P/N 10193836, SEAL THE HOUSING TO THE INNER PANEL BY APPLYING THE SEAL IN THE PATTERN SHOWN IN FIGURE 8, SECTION A-A.

- INSERT ART WORK (FIGURE 8) -

USING AN X-ACTO R KNIFE AND #11 BLADE, CAREFULLY CUT A TRIANGLE SHAPED HOLE IN THE REAR BELT SEAL TO CREATE A DRAIN AS SHOWN IN FIGURE 9, VIEW A. THIS DRAIN WILL MINIMIZE WATER RUNNING DOWN THE INSIDE OF THE REAR WEATHERSTRIP AND COLLECTING AT THE CARPET RETAINER.

- INSERT ART WORK (FIGURE 9) -

GENERAL INFORMATION ON DOOR GLASS ADJUSTMENTS (SEE FIGURE 10A AND B)

NOTE: ON FRAMELESS GLASS, ALWAYS CHECK AND VERIFY DOOR ALIGNMENT TO THE BODY PRIOR TO ADJUSTING DOOR GLASS. SOME ITEMS MAY REQUIRE THAT THE DOOR GLASS BE ADJUSTED. IT IS IMPORTANT THAT THE DOOR GLASS BE ABLE TO CONTACT AND SEAL TO THE WEATHERSTRIP WHEN OPERATING THE GLASS WITH THE DOOR CLOSED ("REROLL"). ALWAYS CHECK THE ABILITY TO "REROLL THE DOOR GLASS" WITH THE DOOR IN THE CLOSED POSITION WHEN DOOR GLASS ADJUSTMENTS ARE MADE.
