Question about Cars & Trucks
Day and night lights don't work only high beam working what could be the reason?
I see two problems that are pretty common either fuse is blown or your headlight switch has failed.

I got my daughter a 2003 Pontiac Sunfire. They are a lot of electrical work.
The problem is the wiring harness which splits and travels under the battery and the windshield washer reservoir. The wires oxidize and fall apart.
The low beams will work but if you turn on the high beams the lights will go completely out, right?
If this is the case I can pretty much guarantee that you will have to remove the battery, the drivers side front inner fender, the air filter housing, the air throat, and the windshield washer reservoir. You will then be able to open the wiring harness feeding the headlights. The wire that feeds your high beams is a pink wire. Test the wires from the harness plug (located just under the battery) to a point as close to the headlight as you can, Use a simple continuity tester. Also feel and bend the wires. If the insulation cracks and you see a green or lite blue powder then patch a new wire in.
All in all I found 4-wires which I replaced. Everything works now.

Need to have an electrical shop determine what is wrong.
It could be a fuse for the low beam headlamps that has blown,
or a relay has been overheated.
Check that the bulbs for the low beam aren't blown out, possibly

The problem is likely your multi purpose signal light switch. If you take the lever and move it from hi to low beam will the low beams come on? It is common for this multi purpose (real expensive ) switch to fail after a period of time! The steering wheel may have to be removed, to change it. The air bags will also need to be disabled so as not to active them while removing the switch.
