Vent Frame, Checking






Vent Frame, Checking

- Check the ventilation channels to both ventilation frames - A - for obstruction (left and right).





• Sealing lips - B - in air extraction outlets - A - must move freely and close automatically.

• Blocked (closed) channels or jammed sealing lips may cause windows to fog up.

• The figure shows the ventilation frame with the rear sedan bumper removed. A different type of ventilation frame is installed in the Avant.

• One vent frame is installed on left and right for forced air extraction.

• To ensure proper function of the passenger compartment ventilation, vent openings - C - integrated in the luggage compartment trim must not be sealed.
