2006 Pontiac Grand Prix Q&A
2006 Pontiac Grand Prix Question: My low beams do not work at all.
Get circuit diagram and test switch and power to switch/control. Test grounds. - ziptie12
i don't know if this will be your problem, but my 2002 chevy impala started out with my low beam not working then the high beams stopped working, my problem was the dimmer switch which is also your turn signal switch. auto zone sells them for $300. but i found a brand new one on e-bay for under $30.00 with a six month warranty. hope this helps you - keithsixpack69
