dodge shadow brake lights

We finally got the turn signals to work on the kids' Dodge Shadow but we cannot seem to get the brake lights to work no matter what we do...anyone ever have this problem ??? or know the solution?

Thanks!

My Shadow had ground problems in both brake and both backup sockets. The ground wire connector has a small tab that "springs" against the body of the socket. All four had lost their springability or broken off. So far I have repaired the tab on the brake sockets with solder and just soldered the ground wire to the socket body on the back ups. Otherwise it's $18 per socket from Mopar.
