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
