My car has 180000 miles.
My car has an automatic transmission.

Hello. Most of the time this is not a harness problem. It is typically caused by an issue with the combination switch. This switch typically shorts internally and causes this. I have also had fuse box issues that have caused this but that is not as likely. The only way to know for sure would to test the circuit with a voltage meter to see where the voltage is lost, which is typically at the switch. If you need help with fixing this taillight issue, consider YourMechanic, as a certified mechanic can come to your home or office to diagnose why the lights are not working.
