Brake lights not working properly

Good afternoon.

It sounds like your switch is worn out and needs to be replaced. I attached a picture and the procedure for you for the procedure.

1. Disconnect and isolate the battery negative cable.
2. Locate the brake lamp switch (4) near the support bracket (1) on the lower steering column.
3. Disconnect the wire harness connector (2) from the brake lamp switch.
4. Rotate the brake lamp switch housing counterclockwise about 30 degrees to align the tabs on the switch locking collar with the keyed mounting hole in the switch mounting bracket.
5. Pull the switch straight back from the keyed hole to remove it from the bracket.
6. Discard the removed brake lamp switch.

Installation:

1. Depress and hold the brake pedal (5) in the depressed position.
2. Align the tabs on the brake lamp switch (4) locking collar with the keyed hole in the switch mounting bracket.
3. Insert the tabs on the brake lamp switch locking collar through the keyed hole in the switch mounting bracket until the switch housing is firmly seated against the bracket.
4. Rotate the switch clockwise about 30 degrees to engage the tabs on the locking collar with the switch mounting bracket.
5. Release the brake pedal.

Caution: Do not release or pull up on the brake pedal before the switch plunger adjustment has been completed.

6. Release the brake pedal, but do not pull it upward.
7. Rotate the plunger adjustment release lever (3) clockwise until it locks into place. The lever should be parallel to the brake lamp switch connector receptacle. This action will set the switch plunger length to a final adjustment position and cannot be undone. If not performed properly the first time, a new brake lamp switch must be installed.
8. Reconnect the wire harness connector (2) to the brake lamp switch.
9. Reconnect the battery negative cable.
