On some 2004 F-150 Supercab vehicles built before 11/12/2003, the rear door panel outer surface may exhibit a wavy appearance in cold weather. The door may also exhibit a loud ringing upon closing, or a rattle noise may be present inside the door.
To service, install a Permacel Mastic Patch (4L3Z-18203A16-AA) to the door outer panel. Refer to the following Service Procedure.
- Remove the rear door trim panel per Section 501-05 of the Workshop Manual.
- Peel back the water shield to access the inside of the door.
- Inspect for the presence of mastic material on the door outer panel. If none is present, proceed to Step 7.
NOTE: THE MASTIC MATERIAL MAY HAVE FALLEN DOWN INTO THE DOOR. REMOVE ANY LOOSE PIECES FROM THE BOTTOM OF THE DOOR.
- From the outside of the door, place an Infra-Red paint curing lamp 46cm (18″) from the door sheet metal surface in the area of the mastic patch. Heat the door for 3-7 minutes at 180°F.
- Remove the heated mastic material from inside the door using a wide putty knife.
- Remove any loose mastic pieces from the bottom of the door.
- Apply Motorcraft PM-12-A Low Temperature Anti-Corrosion Coating to the original location of the mastic material.
NOTE: THERE WILL BE A VISIBLE WITNESS MARK (UNPAINTED PORTION) INSIDE THE DOOR INDICATING THE LOCATION FOR THE NEW MASTIC MATERIAL.
