The brake lights do not work. The brake light above the rear hatch does work. The turn signals on both sides work. What might the problem be?

The fuse box under the hood has the fuse for the brake lights. That fuse is good.
Both filiments work. One for the turn signals/ brakes. The other filiment is for the tail lights. There are two bulbs in the tail light hosing both filiments work in each bulb.
Thanks for your ideas.

Any thing else I can check?

Check and see if there is a fuse for the brake lights. Could be a possible brake switch. Let me know what you find I can see what we can do to help you

What about the Grounds or the Sockets?

I'd also think it's possibly a grounding issue.

If it was a ground issue your 3rd brake light wouldnt work either same circuit

you can check your sockets with a test light
