Standard Procedure - Liftgate Adjustment
WARNING: This page is about a different car, the 2004 Chrysler Pacifica. However, it is still accessible from the selected car via links, so may be relevant.
In order for the power liftgate system to function properly the liftgate must move freely and smoothly. The power liftgate system can accommodate for some minor changes in the effort required to move the liftgate. However, in extreme conditions the liftgate may need to be mechanically adjusted for proper fit and finish. Refer to the Liftgate Adjustment procedure in LIFTGATE for detailed instructions.
If a problem exists with the power liftgate and it is suspected to be extreme effort, check the liftgate prop rods and hinges for free movement. Use a known good vehicle for liftgate effort comparison.
