Manual Latch Release for Power Liftgate
WARNING: This page is about a different car, the 2007 Lincoln MKX and 2007 Ford Edge. However, it is still accessible from the selected car via links, so may be relevant.
To manually open the power liftgate, due to power latch failure, remove the latch access cover located on the lower center of the liftgate trim panel. Reach in and down on the right side of the latch and push down on the manual latch release lever.
