Door Trim Panel Replacement Removal Procedure
Important: To reduce the chance of damage to the trim panel leave the switch in the panel until after the panel is removed from the door.
Notice: Insert the fastener removal tool between the male fastener, which is attached to the trim panel, and the female retainer, which is in the door. Incorrectly inserting the tool between the head of the female retainer and the door will break the fasteners.
Pry out the remaining trim panel fasteners working your way forward.
Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.
