Chevrolet Cruze Repair Manual: Exterior Windnoise
Warning: Refer to Assistant Driving Warning in the Preface section.
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.
