SOURCE: Where is the DRL Module on a 2003 Sunfire?

Fuse panel left side of dash. It's not a typical module it's only a relay. Your instrument cluster has a microprocessor which energizes the relay. In another post someone said there is a resistor behind right headlamp that could be your problem, I haven't as of yet checked the schematics to confirm but sounds right.

Daytime running lights and low beam lights not workin, fuse is fine. Replaced relay lights still don't work.


I just worked on a Pontiac Sunfire on a light issue. The driving lights are on a separate switch on a 2003 from the dimmer switch. Have you checked to make sure both low beam light bulbs for your headlights are not burnt out on low beam? Have you checked to make sure you have power to the low beam where the connector connects onto the bulb?

High beam headlights quit working. Bulbs are OK.


If your getting power at the headlight wire harness, then it's going to be the bulb it self, but make sure your checking the right 12 volt terminal at the plug. There should be three terminals there, there is a ground, 12 volt low beam, and a 12 volt high beam. If both the low and high 12 volts are getting power, then it's going to be the head light bulb it self that has reached the end of it's life time since the day time running lights are always on which is the high beams. Good luck and check the fuse box under the hood by the battery.

High beam lights and driving lights don`t work


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
