Power Liftgate Closes Immediately After Fully Opening - keywords body drop noise open power rear strut switch weak

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.

A customer and/or technician may comment that when using the Power Liftgate, it will open fully, drop a few inches, then power close. There will likely be a loud noise as the clutch engages during this event.

Turn off the Power Liftgate, using the Disable Switch in the bottom of the center stack. Manually open the liftgate to the full open position using the Release Switch on the exterior liftgate pull handle. Verify that the liftgate will remain at or near the full open position for several minutes. If the liftgate will not remain open, replace the liftgate strut(s) that are weak. Though both struts should be inspected for weakness, it is often only the LH strut that requires replacement. It is important to note that the LH and RH Assist Struts have two different part numbers and each should be installed in its proper location.

Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.
