Thread: headlight not working

Hello all, I'm new here. Question - about 3 months back my girlfriend purchased a 2003 Grand Prix. The dealer installed new headlamp bulbs as the driver side wasn't working. 3 months later, the driver side has again quit working. I've replaced the bulb myself now and now it still wont work. Wiring and connector appear in good shape and it's not a fuse. Anything else I may be overlooking?

Thank you.

If the fuse and bulb are good, check power to the connector with a multimeter. If a multimeter shows a drop in power, start checking the headlight wiring, and grounds.

Yea I see that thanks for the info but it is a broad problem your talking multi function switch issue simple ground, relay possibly. suggested the simplest issue but my bad it's been checked wiring problems can be a nightmare deal with either way

I'll slow down and ask for more info the headlight worked for the three months does it appear to be blown high and low beam ?

Finally fixed the problem. Shorted out a wire and the terminal was burnt leading into the fuse box so I replaced that and everything works perfectly now

Alright, I returned to the country after being away for the holiday break. I finally got to see the car again after returning and of course the driver side headlight still doesn't work. In my absence the g/f again had the bulb replaced and of course the Low Beam still doesn't work (her High Beam does). I found and pulled the relay, replaced it (she said do it, I did it) and still no working headlight. She's becoming frustrated that this headlight doesn't work and has already received warnings from police. I'll see the car again this weekend and I'll take a multimeter and test the connector. I checked the connector last time and there was no breaks in the wire or any loose/damaged terminals.

This is what I get for making a 'PROMISE' I'll get to the bottom of this problem and fixing it.

Lol good luck! The cop gave me a week to get it fixed or he would give me a ticket lol I spent hours in the garage till I finally figured it out.
