Pinpoint Test A : The Roof Opening Panel Has Excessive Wind Noise

WARNING: This page is about a different car, the 2017 Lincoln Navigator and 2017 Ford Expedition. However, it is still accessible from the selected car via links, so may be relevant.

  1. A1 VERIFY ROOF OPENING PANEL NOISE

    • Road test the vehicle with the roof opening panel in the CLOSED and OPEN positions.

    Is the wind noise present only in the OPEN position? 

    Yes  GO to  A4.
    No  GO to  A2.

  2. A2 CHECK THE ROOF OPENING PANEL ALIGNMENT

    • Make sure the roof opening panel glass is centered and flush with the roof line.

    Is the roof opening panel aligned correctly? 

    Yes  GO to  A3.
    No  ALIGN the roof opening panel. REFER to Roof Opening Panel Alignment .

  3. A3 CHECK THE ROOF OPENING PANEL WEATHERSTRIP

    NOTE: Make sure the weatherstrip is secured to the glass, not cut, cracked, pinched, loose or obstructed in CLOSED, VENT and OPEN position.

    • Check the roof opening panel weatherstrip.

    Is the roof opening panel weatherstrip OK? 

    Yes  REFER to Body System General Information to diagnose other possible sources of the excessive wind noise.
    No  INSTALL a new roof opening panel weatherstrip. REFER to Roof Opening Panel Weatherstrip .

  4. A4 CHECK THE AIR DEFLECTOR

    • Make sure the air deflector is securely attached and check for torn and unsecured tethers.

    Is the air deflector OK? 

    Yes  GO to  A5.
    No  REPAIR or INSTALL new air deflector assembly. REFER to Air Deflector .

  5. A5 CHECK THE AIR DEFLECTOR FOR VIBRATION

    • Road test the vehicle and check for air deflector vibration.

    Did the air deflector vibrate? 

    Yes  CHECK the curvature of the air deflector. The top center edge of the air deflector should be approximately 6-8 mm (0.23-0.31 in) above the roof line at the center of the vehicle. The curvature of the air deflector may be modified if necessary by slightly bending it upward or downward at its center. TEST the system for normal operation.
    No  PARTIALLY close the roof opening panel until the noise is eliminated. If the noise is eliminated, inform the customer that changing glass location will eliminate the wind noise. If the wind noise is not eliminated, INSTALL a new air deflector. REFER to Air Deflector .
