* Visually inspect them: Have someone else press the brake pedal while you check if the lights in the rear illuminate. Look at both the left and right brake lights.
* Check the brake light switch: This switch is usually located near the brake pedal. It activates the brake lights when the brake pedal is pressed. A faulty switch can prevent the brake lights from working.
* Check the bulbs: If the lights aren't working, the bulbs might be burned out. Replace them if necessary.
* Check the fuses: Consult your owner's manual to locate the fuse for the brake lights. A blown fuse will also prevent the lights from working.
* Check the wiring: This is more complicated and requires some electrical knowledge. A problem in the wiring harness could be the cause.
If you've checked these things and the brake lights still don't work, it's best to take your Town Car to a mechanic for diagnosis and repair. Non-working brake lights are a safety hazard.
