Error Code B3949 Pontiac Montana
I have a 2006 Pontiac Montana with a 3.9L engine. I'm getting the error code B3949. How do I fix it?
Is this a good question?
Does your right front turn signal work ? the letter B denoted body code and 3949indicates right front light signal. There's nothing wrong with the engine you have a problem with the circuit for your blinker. Hope this helps
