Vehicle: 1999 Volvo S70 AWD

Symptoms: Erratic turn signal (Only when turning left.)

Observations: The left front turn signal is out. The left sidemarker works and so does the left rear turn signal.

The right front turn signal works, but it looks dimmer to me then when I installed the bulbs a few years ago. The right sidemarker works fine as does the right rear turn signal.

My only assumption is that since the front left turn signal is burned out it is causing the blinker to go all erratic like. The right blinker blinks normally.

 

Yes that is true try looking at sock and wiring and it maybe grounding out somewhere on the left or right good luck
