* Blown tail light bulb(s): This is the most common and easiest fix. Check both the left and right tail light bulbs.
* Burnt-out tail light fuse: Check your vehicle's fuse box for a blown fuse related to the tail lights. The fuse box location and diagram will be in your owner's manual.
* Faulty tail light switch: This is less likely if your brake lights work, but a partially malfunctioning switch could affect only the tail lights.
* Wiring issue: A broken or corroded wire in the tail light circuit could interrupt the power. This often requires more investigation, possibly tracing the wiring.
* Ground problem: A poor ground connection can prevent the tail lights from working correctly.
* Faulty tail light socket: The socket itself might be damaged, preventing proper contact with the bulb.
Troubleshooting steps:
1. Check the bulbs: This is the first and easiest thing to do. Replace any burnt-out bulbs.
2. Check the fuses: Consult your owner's manual for the location and diagram of your fuse box. Look for fuses related to the tail lights.
3. Visual inspection: Carefully examine the wiring harness for any visible damage or corrosion near the tail light assemblies.
If you've checked these and the problem persists, it's best to consult a qualified mechanic to diagnose and repair the issue. They have the tools and expertise to pinpoint the problem more accurately.
