Use the following inspections in order to aid in
diagnosing wind whistle or wind roar:
1. Note the details for wind noise:
– The perceived location
– The location where the noise is loudest
– When the noise occurs
– The vehicle speed
– The interior fan speed
– The position of the windows
– What the noise sounds like
2. Inspect the vehicle for the possible cause of the
windnoise.
3. Test drive the vehicle and determine if the windnoise
is external or internal.
4. Perform a visual inspection of the following
components:
– Loose fasteners
– Torn weatherstrips
– Broken weld joints
– Sealer and/or adhesive skips
Exterior Windnoise
WARNING
!
Refer to Assistant Driving Caution.
Exterior windnoise is louder when the vehicle is driven
with one or more windows down. Exterior windnoise
occurs when air passes over the body panels, the
seams, or the openings. Use the following items during
the test drive in order to aid in the detection of leaks:
• Mechanic's stethoscope or heater hose
• Masking tape-51 mm (2 in) width
• Strip caulk
• A water soluble marking pencil
1. While driving, determine the location of the exterior
windnoise by lowering one window at a time. If the
location corresponds with the condition in step 2, pull
over and make a temporary repair with 51 mm (2 in)
wide masking tape.
2. Tape over the gaps and the moldings one at a time.
Test between each taping. Taping over the gaps and
moldings will correct the condition.
3. Temporarily repair the condition with masking tape.
Adjust the tape when needed.
4. Continue testing in order to determine if the noise
has been eliminated or other leak areas exist.
5. When all the reported leak conditions are located,
make permanent repairs using the proper alignment
techniques and the sealing materials.
Interior Windnoise
WARNING
!
Refer to Assistant Driving Caution.
Interior windnoise is not heard when the window is
lowered. Interior windnoise is caused by the air leaving
the inside of the vehicle through a seal or a seam.
1. Tape over the relief valves to cause added air
pressure within the vehicle.
2. Test drive the vehicle and listen for windnoise or a
whistle.
3. Pull the vehicle over and make the temporary repairs
using masking tape. If you cannot determine the
source of the windnoise, perform one or more of the
following diagnostic tests:
– “Air Pressure Test”
– “Soap Suds or Bubble Test”
– “Tracing Powder or Chalk Test”
Waterleak Test Preparation
• This vehicle is designed to operate under normal
environmental conditions.
• The design criteria for sealing materials and
components takes into consideration the sealing
forces required to withstand the natural elements.
These specifications cannot take into consideration
any artificial conditions, i.e., high pressure car
washes.
• The water leak test procedure has been correlated to
the natural elements and will determine the ability of a
vehicle to perform under normal operating conditions.
• The first step in diagnosing a leak is determining the
conditions under which a leak occurs. If the general
leak area can be found, the exact entry point can be
isolated using a water hose or an air hose. Some trim
panels or components may need to be removed in
order to repair the leak.
• A leak around a door, or a door window panel does
not necessarily indicate a bad weatherstrip. An
adjustment to the door or door window may resolve
the condition.
