SOURCE: DRL and High Beam do not work right on Honda Accord EX 1998

Some time back I found some data on a similar website suggesting that the Day Light Running circuit board, just under the steering column, developed cracks in some of the soldered joints. Your high beams should also be affected with loss of day light running lights.
Resoldering repaired the continuity of the circuits. Ours is now working quite reliably. Some of the defective areas developed slight brownish discoloration, that's how I was told to recognise the areas to be resoldered. Hope this will help you solve your problem.

SOURCE: Flickering Headlights and Dim interior lights

Definately an electrical problem....first off, check the battery and alternator connections to make sure they are tight. The problem has to be before the fuse box because the headlights and interior lights are on different fuses. It sounds to me like a loose wire, corroded battery terminals, or an alternator that is going bad. An alternator is a relatively easy and cheap fix. They cost about $100 and require removing a few wires, 3 bolts, and the serpentine belt.

2005 pontiac sunfire headlight issue


I have run into a few of these and what I found was water getting into the wires that go to these headlights.The harness is just below the battery area.It will be easier to get to from the bottom of the vehicle.You will have to remove the plastic cover from the harness and the electrical tape.Find the dark blue and the orange wires.The dark blue is for the drivers side and the orange is for the passengers side.There should be 2 of each.Look real closely and see if you see a spot where the wires are slightly swelled up.These wires are only 18 gauge so it is not easy finding the bad spot.One thing you can try is pulling on the wires a little and sometimes they will separate where the bad spot is.Hope this helps.Good luck.

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

When i start my sunfire the service light with a little wrench comes on


the service light with wrench is for service vehicle and is on possibly because there is a burned out light bulb on the exterior. turn lights on and check every light even the license plate light. i bet there is a bulb out somewhere. check every light and hopefully this is the problem.

2003 sunfire wiring


I had that problem, and I thought it was the ground as well, but it turns out the splice in the wire harness sits at the absolute lowest level the bundle could, and it collects water. I opened mine up, and it was completely corroded. It appears there was a recall on this, but if you got yours used, as I did, you wouldn't have been notified.
I fixed that, but my fog lights are out now.
