(2) Apply 50 mm (2 in.) masking tape in 150 mm
(6 in.) lengths along weatherstrips, weld seams or
moldings. After each length is applied, drive the vehi-
cle. If noise goes away after a piece of tape is applied,
remove tape, locate, and repair defect.
POSSIBLE CAUSE OF WIND NOISE
• Moldings standing away from body surface can
catch wind and whistle.
• Gaps in sealed areas behind overhanging body
flanges can cause wind-rushing sounds.
• Misaligned movable components.
• Missing or improperly installed plugs in pillars.
• Weld burn through holes.
STANDARD PROCEDURE
STANDARD PROCEDURE - PLASTIC BODY
PANEL REPAIR
There are many different types of plastics used in
today's automotive environment. We group plastics in
three different categories: Rigid, Semi-Rigid, and
Flexible. Any of these plastics may require the use of
an adhesion promoter for repair. These types of plas-
tic are used extensively on DaimlerChrysler Motors
vehicles. Always follow repair material manufactur-
er's plastic identification and repair procedures.
Rigid Plastics:
Examples of rigid plastic use: Fascias, Hoods,
Doors, and other Body Panels, which include SMC,
ABS, and Polycarbonates.
Semi - Rigid Plastics:
Examples of semi-rigid plastic use: Interior Panels,
Under Hood Panels, and other Body Trim Panels.
Flexible Plastics:
Examples of flexible plastic use: Fascias, Body
Moldings, and upper and lower Fascia Covers.
Repair Procedure:
The repair procedure for all three categories of
plastics is basically the same. The one difference is
the material used for the repair. The materials must
