ISSUE

Power door locks self activate, are inoperative, or remote keyless entry may be inoperative when vehicle is or has been wet. Water leaks onto the rear door power lock switch. This may be caused by:

^ Low torque on the door glass nuts

^ Door glass butyl rope seal off location

^ Porosity in sealant between the door seal C-channel-to-door sheet metal

^ Water entering inside the door from the hinges or check strap

ACTION

Repair leak and/or install water shield. Refer to the following Service Procedure for details.

NOTE
IF THE POWER LOCKS/REMOTE KEYLESS ENTRY ARE INOPERATIVE OR SELF-ACTIVATING AT THE TIME OF REPAIR, APPLICABILITY OF THIS TSB MAY BE CONFIRMED BY DISCONNECTING THE REAR DOOR SWITCH AND RETESTING. IF THE POWER LOCKS FUNCTION NORMALLY, THIS TSB WILL CORRECT THE CONCERN.

SERVICE PROCEDURE

Remove the interior trim halo moulding and door trim panel from the right rear door by referring to the procedures in the 1998 Econoline Workshop Manual, Pages 501-05-11 to 13. Perform the following Rear Door Glass, Door Seal C-Channel, and Door Hinges And Check Strap leak tests and repair procedures.

NOTE
VEHICLE MAY SELF-LOCK DURING WATER TEST. BE SURE KEYS ARE ACCESSIBLE.

REAR DOOR GLASS

Using water hose, direct water around the edge of the right rear door. Inspect for water leaks. If the door glass leaks, retighten nuts to 2.5 N.m (22 lb-in). If retightening the glass nuts does not stop the leak, replace the Rear Door Glass Module (F6UZ-15420A034-AA).

DOOR SEAL C-CHANNEL





Inspect for gaps and holes in the factory applied sealer along the outboard side of the C-channel (Figure 1) (weatherstrip is pulled out of C-channel in Figure 1). Using a water bottle, force water into any hole to see if a leak occurs, allowing water to exit the opposite side of the C-channel. Adjust hose to spray pattern and direct water across the rear end of the roof and at the top of the door. Inspect for water leaks. If leaks are found using either test, reseal the entire length of each side of the C-channel to the door sheet metal using clear silicone sealant.

DOOR HINGES AND CHECK STRAP








The hinges and check strap are not sealed and leaks are always expected. Install a Water Shield (XC2Z-15402A08-AA) to the door sheet metal (Figure 2). Route the switch wiring and connector under the bottom edge of the water shield (Figure 3). Be careful the water shield is not pulled loose by the wiring.
