Lift-gate will not open

Hi and thanks for using 2CarPros.

Since there is no noise, I would suggest first checking fuses. Check the lock and unlock fuse in the fuse panel in the vehicle. Picture 1 shows the panel and picture 2 indicates the two fuses in question.

If the fuses are good, I have a question. You replaced the lift gate motor? Have you checked the power latch assembly?

To access it, you need to normally open the hatch. In this case, you will need to remove the lift gate trim. If that actuator doesn't release, the lift motor won't operate.

Check the fuses first and let me know what you find or if you have other questions. Here are a couple links that may be helpful:

Welcome back:
It sounds like the latch itself is bad. I would suggest removing it, cleaning it, and checking if it will work if power is supplied directly to it.
