| Tail Light Switch problems |
I received a warning on my dashboard that my rear tail light blinker was not functioning correctly. The passenger side blinker was not functioning correctly. Upon testing the hazard lights the blinker was correcting and after restarting the car the light functioned correctly. 2 weeks later I received the same error again, turning off and on the car did not correct the issue. Upon opening the trunk and inspecting the light I noticed the top brown wire that was attached to the tail light harness was blackened and burned as if the wire was overheating and effecting or burning the harness. The tail light still intermittently works on and off however the blackened wires are a concern to me that it could become a fire hazard.
