Donald Devine How to open a stuck Back hatch on 2007 Suburban?
There are a few things you can try to open a stuck back hatch on a 2007 Suburban:
Check the battery in the keyless remote. If the battery is low or dead, the remote may not have enough power to release the latch.
Check the latch itself for any debris or obstruction that may be preventing it from releasing.
If the latch seems to be working properly, try manually releasing it by pulling on the emergency release handle inside the vehicle.
If none of the above steps work, it may be a problem with the power liftgate module or actuator and you should take it to a mechanic or dealership for further diagnosis and repair.
Lubricate the hinges of the hatch door with a silicone-based lubricant to ensure the door opens smoothly.
There could be several reasons why the liftgate on your Acura MDX is not opening all the way. Here are a few things you can try to troubleshoot the issue:
Check the latch mechanism: Make sure that the latch mechanism on the liftgate is not damaged or stuck. You may be able to manually release the latch by pushing on the release button or pulling on the emergency release cord (if your vehicle has one).
Inspect the liftgate struts: The liftgate struts may be worn out or damaged, preventing the liftgate from opening all the way. If the struts are the issue, they will need to be replaced.
Check the liftgate hinges: Make sure that the hinges on the liftgate are not damaged or stuck. If the hinges are the problem, they may need to be lubricated or replaced.
Check the wiring and connections: Make sure that all of the wiring and connections to the liftgate motor and latch mechanism are secure and in good condition.
Check for any foreign objects: Make sure that there are no foreign objects blocking the liftgate from opening all the way.
If you have tried these troubleshooting steps and are still unable to get the liftgate to open, it may be necessary to have the issue diagnosed and repaired by a mechanic.
Did you take it to a qualified repair shop an have the liftgate module checked for DTC'S - diagnostic trouble code's ? Do you know what DTC'S are ? Very complex electronic's .Need a factory or professional scan tool to read these code's .

The liftgate control module (LGM) continuously monitors power liftgate operation and calculates its location and direction of travel using 2 Hall effect sensors that are part of the gear motor assembly. The Hall effect sensors are 5-volt 3-wire sensors and are supplied with a 5-volt power, ground and signal circuits from the LGM. The Hall effect sensor signal circuits are referenced from voltage within the LGM and pulsed low by the Hall effect sensors.
Your best bet ,take it to a qualified repair shop.
Make sure your window latch is sealed correctly,,,,and check the button on the bottom of outside handle,,, sometimes they sticks and will not let the door work right or not at all
I have a 2008 Suburban with the power liftgate disabled. I have had the power latch stop working, and the BCM report that the rear access open when it is closed (both gate and glass). Somehow the liftgate module thinks the gate is open, so I cannot open the gate at all, and the latch and rear wiper will not work. To reset the control module I pulled the liftgate fuse (#20) in the instrument panel fuse box, turned the car on, off, reinstalled fuse, turned car on, unlocked doors using drivers side switch, and the power latch will function again - at least for a while.
The gas charged lift supports are in need of replacement, due to the leak, it loses its strength to fully go up and keep it up,also change in pairs for best results and reliability, they are available from a local parts store.
{: ) Your liftgate struts (shocks) could have gone weak. If it's a power liftgate, press the off button to disable the power liftgate function, so that you can open the liftgate manually. With a little help from you, extend the liftgate at full open position and check if it will hold itself up there as it normally should. If it starts to fall off as you catch it, that means the liftgate struts don't have enough pressure anymore to push and sustain the weight of the liftgate. Check for signs of leak on the struts, or better if you can replace it both.
Try changing the liftgate latch. If you have power liftgate, that is the usual fault by experience. There is also possibility for the other associated components to fail, but they are more costly. You can go for these repair while the gate is not yet stuck closed, so you can easily remove the trim panel. However, I still suggest a preliminary check up on the circuits. The fuses, switches, modules, codes, etc. If the liftgate seems to be operational, except for the proper closing and initial opening, its most likely the latch. I just hope we get lucky on that. Okay, there? goodluck. : )
