1. Confirm the condition exists. Is there snow or ice buildup between the right or left front door and front fender that prevents the front door from fully opening?
YES — Continue to step 2.
NO — This bulletin does NOT apply. Continue diagnosis using the applicable Repair Manual.

2. Clean off the vehicle.
A. Remove the snow.
B. Melt ANY ice using a heat gun.
C. Open the door to a fully open position

3. Place the vehicle on a lift to remove the right or left front tire and wheel.

4. Remove the right or left front mudguard by removing the five bolts.

5. Remove the right or left front fender wheel opening molding next to the door
A. Peel back the section next to the door.

C. Cut a 105-mm (4.1-in.) extrusion section from the RR door No. 3 weatherstrip (do NOT use the injection molded joints)

6. If the vehicle has been exposed to a cold environment for an extended period, use a heat gun to bring the A-pillar section to room temperature (between 60°F – 100°F)

7. Clean the A-pillar section using isopropyl alcohol and allow it to dry for 1 minute

8. Install the weatherstrip extrusion from the door opening side.
A. Pull back 1/3 of the tape for temporary placement. Then starting at the front fender well, remove the rest of the tape to press the weatherstrip fully onto the body side outer panel.
B. Refer to the installation reference points as shown to apply the weatherstrip extrusion section.

9. Apply continuous pressure to the weatherstrip extrusion to ensure proper adhesion (approximately 20 – 30 seconds).
