Rear lift gate will not open and does not make any noise

My rear lift gate stopped opening with the handle. I was out of town and for a few days I could open with overhead switch and remote. Now I cannot even open with remote or overhead switch and there is no noise when I use remote and overhead switch. When I use the remote the tail lights flash but nothing happens with the latch.

Hello,

There are four fuses that run the system we should check first. Here is a guide to help you check the fuses #RIGHT STP TURN, #44, 71 and OBS DET.

Here is the liftgate wiring diagrams and fuse panel locations and identification diagrams. This is so we can see how the system works and where we are losing power

Check out the diagrams (below).

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken
