I bought the vehicle listed above and my brake lights have not worked since I bought it. My parking lights all work. All four blinkers work. Brake lights will not work when I mash pedal. I have replaced the switch, fuses, bulbs, and searched for a broken ground. Since I've started messing with it driver rear taillights have quit working but blinker still good. Please someone help me.

Do you have power at the Stop LP fuse under the hood?

Here is a guide that will help us:

If so, try to cycle the multi-function switch to help clean the contacts. Also check the LT Turn and RT Turn fuses inside the same fuse panel with the brake pedal depressed. Here are the brake light wiring diagrams so you can see how the system works. Check out the images (below). Let us know what happens and please upload pictures or videos of the problem.
