• Incorrectly installed front side door window weatherstrip.
• Wind noise generated from sheet metal openings in the upper door frame.

Correction

Note: In cases where the noise can’t be verified coming from the door, and may be
coming from the rear cab area, see Bulletin #17-NA-151.
Verify the condition and repair following the steps outlined in the Service Procedure
below.

Service Procedure

3806385
3806384

Note: These vehicle models use an inlay door
construction, with the door fitting sub-flush to the body
header by 1-2 mm (0.040–0.080 in).

1. At the two locations (1) shown in the illustration
above, inspect the front door fit as to meeting the
suggested 1-2 mm (0.40–0.80 in) sub-flush
dimension.
• If the door fit meets the sub-flush specification,
no door adjustment is necessary and you can
jump ahead to step #4.
• If the door fit DOES NOT meet the sub-flush
specification, continue to step #2 to start the
door adjustment.

Important: The door header bending procedure is only
suggested for technicians experienced in finessing
sheet metal fits.
2. In conditions where the door header is
outboard the design intent, a 1-2 mm (0.040–
0.080 in) change may be accomplished by bending
the door header inboard.
2.1. Lower the front side door glass.
2.2. Placing one hand at the belt and the other at
the door header, carefully attempt to bend the
door about the belt.
2.3. Recheck the door fit to the body header.

Bulletin No.: 17-NA-258

Important: Do NOT touch the body side hinge bolts or
the door side lower hinge, lower bolt.
3.1. Remove both door side upper hinge bolts (1).

3806392

3.2. On the lower hinge, loosen the door side
upper bolt (1).
3.3. Replace both door side upper hinge bolts with
service bolt P/N 11561763.
3.4. Tighten the new bolts while applying inboard
pressure to the door.

Tighten
3806388

Note: The referenced hinge service bolt (2) is
non-shouldered and will allow more adjustment than
the original shouldered bolt (1).

Tighten the bolts to 25 Y (18 lb ft).
3.5. Verify the door fit and tighten the remaining
bolt. Verify proper torque on all four door side
hinge bolts.

3. If bending the door header does not resolve the
condition, the door fit must be adjusted by adding
two hinge service bolts, P/N 11561763.

6.7. Inspect the upper door frame metal glass run
channel, just forward of the B pillar, for
possibly being out of design location.
• If the metal run channel is approximately
the same depth across the top (1), no
additional repair in this area is needed, and
you can move ahead to step # 8.
• If the metal run channel is approximately
1.5 mm higher (up/down) (2), continue to
step # 7 to add foam tape.

Note: Applying GM Glass Cleaner, P/N 19287404
(Canada P/N 8865156), or even plain water, to the
weatherstrip will allow the part to slide and be
re-positioned more easily during installation.

window, and the front window weatherstrip. . Refer
to Front Side Door Window Weatherstrip
Replacement in SI. AND ALSO utilize the
additional detailed steps below.
8.1. Position the weatherstrip to the door frame
and insert the front A-pillar leg down into the
window opening of the sheet metal.

4846299

8.2. Starting at the B-pillar upper corner, position
the corner locator (1) on the weatherstrip to
the hole in the sheet metal (2) and push until
locator snaps into place. An audible click
should be heard when the locator engages.
Tip: Check to verify the weatherstrip is securely in
place by lightly pulling down on the rear leg, and
looking for any movement at the upper corner.

8.3. Fully seat the weatherstrip into the door frame
at least a hand-width forward AND downward
from the B-pillar corner.

8.4. Moving to the A-pillar, match the corner radius
of the weatherstrip (1) to the door frame
radius (2), and push into position.

8.7. Return to the A-pillar and fully seat the front of
the weatherstrip down into the window
opening. Ensure that the larger front lip is
positioned outside the sheet metal.

4846303

8.5. With front and rear corners in place, starting
at the front, fully seat the weatherstrip into
position in the door frame header.
Tip:
With the weatherstrip legs still loose, any gapping at the
header can be adjusted by slightly pulling down on
the legs.
8.6. Once the header is in proper position, fully
seat the weatherstrip at the rear of the door
frame.

4846308

8.8. As a final position check from inside the door,
ensure the B-pillar upper corner tab of the
weatherstrip is centered to the corner of the

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these
technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper
service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions, and know-how to do a
job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to your vehicle, or that your
vehicle will have that condition. See your GM dealer for information on whether your vehicle may benefit from the
information.
