Tools Required:
•

Plastic trim tool

•

Pair of wire cutters taped to protect the vehicle finish as shown OR a small trim clip removal
tool as shown below (e.g. Snap On ASG185B, also taped)

•

1/4 or 3/8 drive 10 mm socket, ratchet & Torque Wrench

SERVICE PROCEDURE / INFORMATION:
REMINDER: Customer satisfaction and retention starts with performing quality repairs.
The service procedures for weatherstrip replacement remain unchanged. Always refer to STIS and
review the full requirements of the repair being performed. The Service Manual procedures contain
information critical to performing an effective repair the first time, every time.
•

Remove the 10 mm hex bolt securing the door checker to
the body side of the door jamb. This bolt has to be removed
as the weatherstrip positioned between the checker and the
door hinges. Once this bolt is removed, use CAUTION
when moving the door to avoid over-extending which will
cause damage. It is also strongly recommended to avoid
working in windy areas.

•

Using the plastic trim tool, insert between the door frame
and weatherstrip then CAREFULLY twist it to release the
2 molded-in weatherstrip retaining clips as shown below.
One clip is located at the top rear corner, the other in the top
front corner.

HELPFUL TIPS:
a Use a corner as the starting point for both the removal of the original and installation of
the new weatherstrip.
a While removing the original weatherstrip, take note of how it is tucked into the channels at
the top and back edges of the window frame to make installation easier.
VERY IMPORTANT: The holes in the doors for these 2 clips are square. When installing the new
weatherstrip, always confirm the retaining clips are properly aligned with the square holes BEFORE
trying to push them into place. The clips are not serviceable separately and can crush or break if
caution is not used when installing them.
•

Remove the original weatherstrip from the retaining T-clips securing it by CAREFULLY
pulling the weatherstrip is one direction only enough to release it from one side of the “T” then
unhooking it off the other side as shown in the sequence below. The replacement weatherstrips
come with new T-Clips already installed.

•

Pull the rest of the weatherstrip from the channels at the top and upper front edge of the door.

•

Use the taped wire cutters or trim clip removal tool to CAREFULLY remove the T-Clips.
When cutters are used, use caution to not cut the clips by squeezing too tight. “Rock” the cutter
side to side or (if a trim clip tool is being used) pry to release but not break them. Any broken
clips must be retrieved from inside the door to avoid possible rattle concerns.

•

As shown earlier, start in the upper front corner when installing the new weatherstrip.
REMINDER: Make sure the 2 molded-in retaining clips are properly aligned with the square
holes in the door frame BEFORE pressing them into place.

•

With the top front corner locked in place, start working the new weatherstrip into the channels
along the top and upper front edge of the door CAREFULLY using the trim tool as shown
below in (Fig. 1). Fig. 2 shows the trim tool being used to tuck the outer lip of the new
weatherstrip under the molding of the door frame. Do not overlook this important step.

•

After confirming alignment with the square hole in the door, press the front molded-in retaining
clip into place.

•

Make sure all the new weatherstrip’s T-Clips align with their respective holes BEFORE
starting to push them into place. Removing them without damaging them to re-position the
new weatherstrip B be avoided. When all are installed, as a final check, go back over each
one by lightly tugging
on the weatherstrip as
shown here to confirm the clips are fully seated tight against the door frame.

•

Reinstall the door checker hex bolt, torque to 33Nm (24 ft. lbs.) to complete the procedure.
