What would cause both of the headlamps to stop working on a 2006 Pontiac Grand Prix?
The parking lamps come on but no headlamps. The high-beams work but not the low beams.
The fuses are ok, (there is 1 fuse for each lamp). Could it be the low-beam relay? Or if 1 headlamp burns out,do both stop working?

most likely faulty LO BEAM Relay, located in the underhood fuse block. if relay tests OK, suspect faulty headlamp switch.
