How to proceed will depend on what you meant by not getting any power to my trailer.
If the 12-volt accessory power pin that's in the 1:00 position on your 7-way isn't active, you'll want to check the fuse in the power distribution box on the inside drivers side fender in the engine compartment. Remove the cover, and locate the two studs on the inboard side of the fuse block. The stud closest to the front of the truck should have a wire with a ring terminal fixed to it. If not, you'll find the wire bundled up under the master cylinder. Attach the terminal to the stud and make sure the adjacent 40amp fuse is in place.
I've provided a photo showing the distribution box from an earlier model GM truck. The box in your truck will be similar, and the fuse will be right next to the stud but the fuses will look a little different.
I checked the owner's manual and couldn't find any reference to a fuse in the block on the side of the dash being involved with the trailer accessory power feed. If you're saying that none of the trailer turn signals/brake lamps or running lamps are working, those fuses are located under the dash to the left of the steering column.
