Try replacing the bulb. It's not a terrible job.
Another thing to check is for a bad ground connection.
headlights and dash lights in 2001 sunfire wont turn on.
Probably your alternator.
voltage regulater on the alternater is going bad
check the fuses - there is no fuse for the headlights.
Under the hood right by the light housing there should be a knob that you can turn manually to open the headlights
in 1986 the headlights weren't fused the likely suspect would be the dimmer switch if it was located on the floor.
The horn on a Pontiac Transport is located in the engine compartment on the passenger side of the vehicle. It should be right behind the passenger side front headlight.
The fuel filter is located under the Pontiac G5 by the rear passenger wheel!

I need help too, but I know you need a 9007 lamp.
Go to Autozone, when you purchase the bulbs, they'll put them in for free
You can find these headlights online, but aftermarket headlights still will cost you a pretty penny, if your grand prix has plastic headlights and it is just a matter of discoloration this could easily be fixed. Just go to the The Headlight Solution, at headlightsolution.net they specialize in restoring / cleaning headlights to like new condition.
