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).
