Driving lights and high beam not working - Sunfire Pontiac Cars & Trucks

It could be driving lights mode instead of low beam. Check connections.

replace the faulty light switch

Well the high and low beam lamps use the same fuses, and the dimmer switch handles the ground circuit. So I would check the dimmer switch if both high beam bulbs are ok.

if you hook the driving lights to the low beam circuit you will be in breach of traffic regulations the regulation reads that driving lights can only be operated with high beams and on selection of low beam , the lights have to go out
added to that is the clause --the driving lights most be extinguishable when on high beam by the use of a separate isolation switch
now the circuit is really simple
you place a relay for each driving light in a suitable place
you run a fused wire from the battery to the relay and then to each light
to make those relays work you connect a wire from the existing high beam relays connections(m piggy back or like connection) so that when on high beam the trigger power that puts the headlights on also triggers the driving light relays
Now to meet regulations you run ground wires for the driving lights back to a switch in the cabin then to ground

Common problem, there is a headlight relay in the power distribution center under the hood that needs changed out.

it is illegal in europe/japan for these foglights to work on anything BUT low beam.as the light spread from these would be defeated if main beam were on in foggy situations.in other words pointless having them switched on.you could always fit accesory spots/driving lights.(like rally cars)but these MUST only come on with high beam.(so you dont blind oncoming traffic.)

high low switch is gone or both low beams bad

just replace the dimmer switch under the column its wore out on the low beam side

yes there is but it is probably da bulbs

Replace the high beam switch, it is part of the multifunction switch.
