Q: Signal light not working

asked by on

My left signal light is not working.

If only the left signal is not working, suspect a faulty bulb. If a replacement bulb does not fix the problem then the circuit is lacking either power or ground. In this case, electrical diagnosis will need to be performed. However, I suggest you try having the bulb replaced first. A professional, such as one from YourMechanic, can inspect your turn signals to make sure that the proper repairs are completed.
