# WINDNOISE/HOOT AT FRONT UPPER DOOR FRAME (ADJ. UPPER DOOR)

#### SUBJECT: Windnoise/1-Hoot at Front Upper Door Frame (Adjust Upper Door Frame)

#### MODELS AFFECTED: 1993 Saturns

CONDITION: Some customers may comment about a loud windnoise sounding like a hoot (similar to blowing across a bottle top) when the vehicle is driven at highway speeds and/or in strong crosswinds.

CAUSE: A low-pressure pocket forms around the upper front door frame area (refer to illustration on next page), and becomes larger and stronger at highway speeds or while driving in strong crosswinds. This low - pressure pocket pulls the front side door window secondary weatherstrip away from its sealing surface, creating a loud "hoot" type windnoise.

This windnoise is most likely to occur on doors that are misadjusted with the front side door window secondary weatherstrip only slightly touching the windshield and/or drip rail molding surface at the upper front door frame area.

CORRECTIVE ACTION: Adjust the top of the door frame inward so that the front side door window secondary weatherstrip is flush-to-slightly concave in appearance using the following procedure.

#### PROCEDURE:

--------- CAUTION: FOR SAFETY REASONS AN ASSISTANT SHOULD DRIVE THE VEHICLE WHILE THE TECHNICIAN CHECKS FOR THE LOCATION OF THE REPORTED CONDITION.

#### NOTICE: Safe legal speeds should never be exceeded.

1. Road test vehicle to verify concern.

2. Check the front side door window secondary weatherstrip appearance.

3. Open door and lower door glass to the full-down position.

#### NOTICE: Care should be taken not to over-bend the door window frame which could impair door glass operation or door closing. It is better to adjust the door in small increments to achieve the flt required.

4. Grasp the upper front portion of the door window frame shown in the following illustration and carefully pull inboard.

5. After a slight adjustment has been made, close the door and check the fit and appearance of the front side door window secondary weatherstrip along its mating surfaces (refer to illustration on page 2).

6. Repeat Steps 4 and 5 until desired adjustment is attained.

7. Check glass operation by raising and lowering the window glass. Also, check door operation by opening and closing the door to make sure it operates correctly.

8. Road test to verify the repair.
