On all automatic lift gates you have an ecm that operates the rear lift motor module that opens and closes the rear gate. If it goes up and makes a grinding noise and then goes back down. Its more than likely that one of the gears have stripped on the module not making it able to lock itself into position. If the gate is operating speratic you may want to have a dealership check out the ecm that operates the lift gate and program you another unit, for instance if it goes up perfectly one time and then goes half way up and then closes. These automatic lift gates can be broken easily by the bag boy at the supermarket by trying to force the gate closed by hand causing the gears to strip. Hope this helps.

Try removing your shocks/struts for the lift gate. once removed, check to see if they fully extend in and out of the barrel. You may have bent shocks/struts. Also, check to see there is nothing preventing the lift-gate from opening such as a bolt or acorns between the spoiler and the roof...

Might need to adjust rear door latch, or could be bad relay or switch. Try pulling/pushing on rear door while closed to see if you can set this off while sitting still.

2007 Yukon Denali XL lift glass is opening when I use the fob to open the rear hatch. This causes me to be unable to then close the rear hatch via the fob


This sounds like you have a grounding problem with your hatch circuits. This type of malfunction usually occurs when two systems (the hatch lift and the Lift glass release) are supposed to be sharing the same ground, but one of the systems has a bad connector or a broken wire. It then "activates" the other system by grounding THROUGH the system that it is supposed to be sharing ground with.

What I would do in your case is to take a HARD look at the wires that are in the conduit that runs between the lift gate and the body. These wires flex every time the lift gate is opened and closed, and are prone to breakage.

The way you describe it, it sounds like the lift gate motor is losing contact at about 1/3 to 1/2 of the way up, and that is when it grabs ground through the glass release solenoid.

Liftgate will not stay open. When you push button it opens fully, but then immediately closes


HilAry when the lift gate goes to the open position does it make a grinding noise when it reaches the fully opened position and then closes, If so the gear driven assembly may have had a tooth broken on one of the gears and has striped out causing the gate to fall back down. If this is not the case meaning there is no grinding noises coming from the gate then you have a ecm module that operates the functions of the gear driven unit telling it when to stop and go down. If this is the problem you might want to take it to the dealership to program the new unit. I hope this helps.

Our back door on our 2007 Toyota Sienna will not stay closed. It will open automatically when we hit the remote. It will go all the up, then it comes right back down.


There was a safety bulletin by Toyota regarding the lift gate of the 2007 Sienna. I had to jump into the cargo area once to avoid being crushed by the lift gate coming down unwantedly.
Contact your dealership..they replaced the lift gate hydralics (under warranty at the time) and the problem was solved.

Check on the Strut Assembies on Each side of the Door. There should be a Safety device on them that will allow you to keep the door up, They could be Catching at the Open Position.
