07 Headlight Issue

The other day my Driver's side dim light started flickering while I was driving, then went out. I replaced the bulb and it is still dead. However, when I wiggle the wiring behind the headlight I can get it to turn on. My question(s) is/are

1. Can I fix this problem myself without too much trouble?

2. If not, how much would it cost to get it fixed and where should I take it?


Also, hello to everyone.

Yes you should be able to isolate the problem and fix it yourself. If moving the wires turns it on and you have no problem with the highbeam you know it's not the ground.,so only leaves one orange wire or tan/white if it's from fuse block.

Thanks! Now I just have to ask, how would I go about fixing the wire(s)? Would it be a job of cutting them and firmly putting them back so they aren't loose (if they are) or would it be more difficult than that?

you could cut a headlight plug out of a parts car and then slide a piece of heatshrink over each of the three wires.Just solder the wires togther and then slide the heatshrink over the connections and wa-la, plug fixed and waterproof seal

It is more likely the connector on the harness in the back of the headlight. You can try cleaning it, recrimping the female connector so it grabs a bit better and add dialectric grease to stop the moisture from getting in. Or like money_man says you might have to replace connector altogether if this fails. I've just noticed mine while check for your issue are starting to pit. Thanks for bringing up this point.

Ok, I'll give it a look and see what needs to be done tonight.

I don't mess with wiring too much (I have in the past, but not for cars) but I assume I should remove the battery cables (or at least the positive cable) before messing with the harness for fear of a short/giving myself a nice Einstein hairdo, correct?

No need to disconnect battery to play with the headlight harness. Only 12Volts max. No computers being played with in this area. I forgot to mention that it might just be a retracted pin in the headlight harness connector like this one. In this case it is the ground that's retracted but in your case it might be the orange.

They should all be equal length inside this connector if not push them in.

If it doesn't clip in position maybe the tab is bent.

In this case just take a small screw driver and gently bend it back into place.


Then re-insert till you hear the clic. You might want to tape tight all five wires together right at the connector so none of the wires pull out when you push the two halves back together.

Ahh, ok! Thanks a ton for the pictures! I'll definitely have an easier time doing this now! I'll try and remember to post what the problem is/was and what I end up doing.

Ok, so I thought I had it fixed. It turned out to be a loose wire attached to this smaller connector about a foot down the wiring from the actual headlight, hopefully this picture will work...


It seems that when that jiggles around freely (whenever I hit a bump or something) my left dim light will flicker, but my brights work perfectly. I think I'm too the point of just taking it to a mechanic unless someone on here knows how to fix it.

If I do take it in, how much can I expect to pay seeing as how it's just a loose wire? Also, would I be able to take it to anyone other than the dealership? I'd like to not pay $300 to get something small like this fixed.

oh no...dont take it in , if it is a break in the wire just do what money man said .. cut it at break.. peel back plastic coating on wire perhaps 1/2 an inch on both ends( or 2 cm..I'm learning uro terms) slide a peice of small heat shrink wrap on one side of wire make sure heat shrink wrap is long enough to cover all exposed wire and some past exposed wire.. solder ends..slide heat shrink to cover exposed wire..heat the heat shrink wrap and wa-la your done.. you guys agree , pretty easy fix. perhaps worse thing would be how easy access is to break spot.
