Good question for the question! There is only one part that can make this happens which is a bad multi-function switch. Here is how to change it out and I have included the brake light wiring diagrams so you can see how the system works.
NOTE: On models with tilt column, unscrew the tilt lever and remove.
REMOVAL AND INSTALLATION
1. Remove steering column shroud.
2. Remove switch to steering column tube casting attaching screws, then disengage switch from column.
3. Disconnect switch electrical connectors.
NOTE: Do not damage PRNDL cable.
4. Remove switch assembly.
5. Reverse procedure to install. Torque switch attaching screws to 18-27 inch lbs.
