Buick Encore: Air & Wind Noise - Repair instructions
EXTERIOR WINDNOISE
WARNING: An assistant should drive the vehicle while the technician
checks for the
location of the reported condition. Otherwise, personal injury could
result.
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
- 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.
- 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.
- Temporarily repair the condition with masking tape. Adjust the tape when
needed.
- Continue testing in order to determine if the noise has been eliminated
or other leak areas exist.
- When all the reported leak conditions are located, make permanent
repairs using the proper alignment
techniques and the sealing materials.
INTERIOR WINDNOISE
WARNING: An assistant should drive the vehicle while the technician
checks for the location of the reported condition. Otherwise,
personal injury could
result.
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.
- Tape over the relief valves to cause added air pressure within the
vehicle.
- Test drive the vehicle and listen for windnoise or a whistle.
- 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
