What would cause 1989 Toyota Camry brake light problems?

1. Faulty brake light switch. The brake light switch is a small switch located at the top of the brake pedal. When you press the brake pedal, the switch is activated and sends a signal to the brake lights to turn on. If the brake light switch is faulty, it may not send a signal to the brake lights, causing them to not work.

2. Blown brake light fuse. The brake light fuse is a small, cylindrical fuse located in the fuse box. If the brake light fuse is blown, it will not allow electricity to flow to the brake lights, causing them to not work.

3. Faulty brake light bulbs. The brake light bulbs are the small, round bulbs located in the brake light housing. If one or more of the brake light bulbs are blown, the brake lights will not work properly.

4. Faulty wiring. The wiring that connects the brake light switch, fuse, and bulbs may be damaged or loose, preventing the brake lights from working properly.

To diagnose the cause of the brake light problem, you will need to inspect the brake light switch, fuse, bulbs, and wiring. If you are not comfortable doing this yourself, you can take your vehicle to a qualified mechanic.
