Since you have checked the fuses and bulbs, and they are both in working condition, the next step is to troubleshoot the brake light/stop light switch. Here are some steps you can take:
1. Inspect the Brake Light Switch:
Locate the brake light switch. In the 1999 Honda Accord, it is usually mounted on the brake pedal assembly.
2. Inspect the switch for any visible signs of damage, such as cracks or loose connections.
2. Test the Brake Light Switch:
Disconnect the electrical connector from the brake light switch.
Using a multimeter, set it to the continuity or resistance mode.
Connect one probe of the multimeter to the terminal on the brake light switch that connects to the brake pedal, and the other probe to a good grounding point on the vehicle.
Press and release the brake pedal. If the switch is working properly, you should hear a clicking sound from the switch as you press the brake pedal, and the multimeter should show continuity or a low resistance reading when the pedal is depressed.
3. Check Wiring Connections:
Inspect the wiring harness and connections between the brake light switch and the brake lights.
Look for any loose, damaged, or corroded connections.
If you find any issues with the wiring, repair or replace the affected components.
4. Check Reverse Light Switch:
If the issue is only affecting the reverse light, you may need to check the reverse light switch.
The reverse light switch is usually located near the transmission or shifter assembly on the 1999 Honda Accord.
Follow the same steps as mentioned above for the brake light switch to inspect, test, and repair the reverse light switch if necessary.
5. Replace the Brake Light Switch or Reverse Light Switch:
If the switch is faulty or the wiring is damaged beyond repair, you will need to replace the brake light switch or reverse light switch, as applicable.
Use OEM (Original Equipment Manufacturer) or high-quality replacement parts for reliable performance.
Note:
If the brake lights and reverse lights still do not work after following these steps, there might be an underlying electrical issue or a problem with the brake light relay. In such cases, it is recommended to consult with a professional mechanic or auto electrician to diagnose and fix the issue.
