Seats - Third Row
The third row seat:

• is three-passenger seat.
• a 60/40 bench seat.
• folds down for more cargo area.
• has optional power fold down seats.

Third Row Power-Fold Seat
CAUTION: To prevent possible damage to the third row seat or the safety belts, make sure that the safety belts are not fastened when moving the seat to the load floor position.
CAUTION: Make sure that no objects such as books, purses or briefcases are on the floor in front of the third row seats or on the seat cushion before lowering the backrest(s).
The third row power-fold seat consists of the following electrical components:

• right third row seat relay.
• left third row seat relay.
• right power-fold seat motor.
• left power-fold seat motor.
• right front third row seat switch (if equipped).
• left front third row seat switch (if equipped).
• right rear third row seat switch.
• left rear third row seat switch.

For the third row power-fold seat to operate, a shared ground is supplied by the body security module (BSM) to both of the power-fold seat relays, enabling the seats to then be moved by pressing one of the third row power-fold seat switches. The third row power-fold seat operates only when the vehicle is in PARK and the liftgate glass, liftgate door or any entry door must be open.
The third row power-fold seat motors transfer movement to a drive gear assembly to raise and lower the seat backrest. The power-fold seat motors rotate a short drive cable which is connected to the drive gear assembly.
The relay's are located in Aux. relay box #2

Replace the LCD cable. Not expensive and easy to replace. Try eBay for a replacement.

Call the dealership and ask them how to reset the electronic on your Ford Expedition after changing the battery. Anything else is happen? Maybe like the radio wont turn on, hit the turn signals and the windshield wiper turn on. ***** things happen after replace the battery. I know what it is, it the darn wigits. GB you....stewbison

CCD Problem. Go to this site: www.CamerasAndParts.com They have a fix for this problem on the G12. They are super for help with the Canons.

When you installed the driver did you check the boxes for the installed options? Plus you may have to check the box for saddle unit. Hope this helps.

try to reprogram it..or change your flex cable.

what seems to happen with these units is the connectors on the screen go bad from opening and closing numerous times. it sucks but thats what happens with these units. everything else will work but the screen goes blank because it doesn't have a good connection with the docking part of the unit
