First check the R/S headlight fuse in the dash fuse panel (left side), second make sure the R/S low beam headlight bulb filament isn't blown, both these scenarios will do what you are saying. The DRL's work when both low beam lights are in series, thus only 6v going to each bulb at reduced brilliance. The high beam is a totally separate circuit controlled by the multifunction switch. The DRL relay is controlled by the Body Control Module, grounded there, and it will also illuminate the service vehicle soon light. It could also be a bad ground at G204. Its on the steering column support bracket.
you have a wiring problem, look up cavalier headlight wiring on the internet, there is a harness connector under the battery that sometimes goes bad, or the wires are broken inside the insulation, usually in the front harness, the head lights hi and daytime lights are controlled through the ecm and low beam is on a separate circuit, i have also found problems in the switch or the drl module in the fuse box, any mor questions mail me
Check the Pink wire for high beams and the Dark Blue wire for low beams. Common locations for wiring problems are behind the headlights,
under the battery tray. Check for a corroded wiring harness connector
or wires at this location. If the wires or connections are found to be
corroded, repair or replace the wire or connector as necessary.
Check for corroded wires. The wiring harness starts under the battery tray and sometimes the battery leaks acid on the connector and corrodes it. If the connector looks good and the bulbs are good then more than likely the harness is rubbing between the washer bottle and the body creating an open or short to ground in either the pink wire or the blue wire to the headlights.
You may have a broken or corroded wire, pull open the wire loom that protects the main lighting wire harness behind and around the drivers side headlight area under the hood. There are splices that are known to trap water in them and short out or turn green. Let me know if you need more clarification?
Hi, 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. Good Luck, Jay
