I own a 2000 sunfire(4 door) and the dash lights, fog lights and the trunk lights do not work. I do have the break lights, all turn signals, head lights, high beams working. I have changed the fuses and bulbs in the trunk. I had a friend connect to the computer and no reports dealing with electrical issues. If anyone could help with this issue I would be happy that I would not have to take a cab to work any more.

You headlight lamp have a diffuser mechanism which allows it to flip between the hight beam and low beam feature of the bulb. In fact, you high beam will function even if the low beam is not working.

I would recommend the purchase of the new headlight lamp. It would cost you you any where from $15.00 per unit to get a replacement lamp

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.
