How do I replace lift gate motor on 2008 Nissan quest?

Did you turn the auto open button off ? It is one of the buttons on the roof console by the phone icon. Does the tail gate open?

Remove the gate, unscrew the hinge, replace all.

It is hidden behind the side panels. You have to remove the rear seats. The panels mostly just pop off. But remove the access panels to find hidden screws. When pull the panel/s, if they don't want to come off with force, mostly there is a screw close by.

Will require a scan tool to check for codes, make sure latch is working well, make sure release switch is getting signal. Most common concern is the latch itself though

I purchased a 2005 Quest that had same damage on the rear lift gate. If I crossed my eyes and pressed down on the magic spot 3% of the time I could get the door to close in a way the sensor would recognize so I didn't have the door open light turn on.

Too fix this problem I removed the interior panel from the lift gate which allows access to the the lock and some of the wires. almost directly behind the licence plate you have access to the inside the lift gate you should see 2 wires that appear to be going down the latch. I'm assuming one of these controls the power locks and the other is for the feedback sensor that tells the car the door is open.

on the drivers side of the opening that exposes the wires going down to the lock you will see there is a white connection for 1 of the 2 wires that is mounted to the inside of the lift-gate. All I did was squeeze and separate this connection and the car no longer recognizes the door is open.

I don't have an alarm so I don't know if this would mess up the alarm other than if someone broke in through the lift gate it wouldn't trigger the sensor.

I hope this helps

replace the beeper that makes the sound when you are in reverse.the light will also go out after you replace thet beeper.

check the hydrolic struts on the lift gate

The lift gate motor needs to be replaced. Preferably at the dealer ship. Its a pain to replace and most shops will do shoddy work and destroy your interior when doing it.

More than likely the lift gate motor has failed.
