ISSUE
Some 2000-2003 Expedition/Navigator, 2001-2003 F-Series Under 8500, and 2003 F-Series over 8500 vehicles may exhibit a rattle from the root
opening panel (moonroof) area, a failure of the roof opening panel to open properly, or a water leak from the roof opening panel. This may be due to the
water trough being separated from the trough guide on either side, as a result of a broken trough guide.
ACTION
Check if the water trough is securely attached to the trough guide at each end. Check for damage to the lifter arm assemblies at the joint where the trough
guide metal rods attach. Refer to the following Service Procedure for details.
SERVICE PROCEDURE
NOTE
IF ROOF OPENING PANEL SERVICE IS PERFORMED BY A SUBLET FACILITY, MAKE SURE THIS ARTICLE IS REFERENCED
DURING SERVICE.
The trough guide is a small plastic piece with a metal rod attachment which is responsible for guiding the roof opening panel water trough along the roof
opening panel track as the panel opens and closes.
The roof opening panel water trough is a metal tray that attaches to the trough guides at each end and is responsible for collecting water as the glass
panel tilts and operates.
In cases where a water trough becomes loose, it will rattle against the rearward portion of the roof opening panel assembly during driving. Likewise, it
may result in the roof opening glass opening without the interior shade opening simultaneously. It may also prevent the glass panel from fully opening or
closing.
A separated water trough may lead to a water leak into the vehicle at the rear of the roof opening glass when the moonroof is opened.
Check if the water trough is securely attached to the trough guide at each end. Check for damage to the lifter arm assemblies at the joint where the trough
guide metal rods attach.
Before replacing the guides and trough, inspect the roof opening panel track for broken plastic guide pieces, and remove them. Be sure to discard the
original water trough and use a new trough, even if damage to the trough itself is not apparent. The new water trough design has fully enclosed screw
holes rather than open-ended slots for securing it to the trough guides.
If there is no damage to the lifter arm assemblies, but the water trough and guide are separated on either side, replace BOTH trough guides AND the
water trough (serviceable subassemblies of the roof opening panel assembly) according to the following replacement instructions.
If there is damage to the lifter arm assembly or assemblies, replace the moonroof assembly according to Workshop Manual Section 501-17.
