SOURCE: The rear power lift gate
You most likely have a failed switch in the rear gate jamb. This switch tells the system that the gate is closed and if the system thinks that the door is already open, it will not open it again.
Have the Body Control Module (BCM) scanned for codes and live data with a scan tool capable of accessing this information. This will tell you if the switch is operational by manually operating switch while monitoring the switch state with the scan tool.
Any shop with a decent scan tool should be able to do this. Nissan dealerships use Consult-II and now Consult-III scanners and have access to stuff the aftermarket guys don't get, but this should be accessible by nearly any higher end scanner like a Snap On Ethos, Solus, or Modis.
Hope this is helpful!

SOURCE: The liftgate will not stay open. There is fluid showing below the support cylinder on the drivers side. I believe the cylinders are shot and need instructions on replacing ford freestyle lift gate sup
for the most part there are small clips top and bottom of the cylinders use a small screw driver and pry the clips out and remove be sure to put a broom handle under the hatch or have someone to hold it up why you are replaceing them so the lift gate does not fall on you.

Check all the fuses under the hood and under the dash. Then try having someone wiggle the liftgate while you "tap" the down button repeatedly. Do not apply too much force to the liftgate.

To open the lift gate manually, use the door unlock switch located
on the drivers door. This should unlock the lift gate as well. Go to the lift
gate and lift the handle to open the rear gate.
Your power lift gate is computer controlled. Sometimes there will
be a faulty input sensor or part that will show the incorrect data to the computer,
therefore the computer will not go through its normal functions.
In most cases its the problem of lift gate latch assembly.
To get it tested and confirmed there is a troubleshoot guide
provided by the service center. To perform this troubleshooting guide you will
require a scan tool to diagnose the exact problem.
the troubleshooting procedure is as follows:---
Please use the following information below when diagnosing an inoperative
lift gate. Disconnect the connector at the lift
gate latch assembly. With the lift gate latch connector disconnected, the 3
signals for the ratchet, pawl, and the sector should be inactive on the scan
Install a 3A fused jumper wire between each signal circuit
terminal (for the pawl, sector, and ratchet) and the ground circuit terminal 2.
Monitor the scan tool as each individual circuit is jumped to ground, the scan
tool should read "active".
If either tests above fails, check the wiring for the signal
circuits, low reference circuit, or try a power lift gate control module from a known good vehicle. If both tests above pass, monitor the internal switch inputs in
the lift gate latch assembly for proper operation.
3. A) with the lift gate in the open position, the ratchet and the
pawl should read "active" and the sector should read
B) With the lift gate in the secondary latched position, the pawl
should read "Inactive" and the ratchet and sector should read
C) With the lift gate fully closed, the pawl, ratchet, and the
sector should all read "inactive".
4.If one of the internal lift gate latch assembly switch inputs
are not reading correctly in one of the positions above and the vehicles passes
test 1 and 2 above. Replace the lift gate latch assembly.
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.
This should help you.Thanks.Helpmech.
