Good day all.
I have a 2004 Frontier. I just purchased used. Well, the headlights are behaving strangely. I will try to list all I know below.

-High beam indicator always on
-fog lights work
-when high beams are switched all lights go out
-low beam lights are HID
- low beams have multiple bulbs surrounding he large center bulbs
- perimeter low beam lights work, but center bulbs do not- when i switch the high beams, all lights go out, except the perimeter lights
- all fuses in tact
- interior lights functioning, except the shift indicator light

PLEASE HELP!::wink::

Check both ground and if the harness is melted somewhere.

My first '95 Hardbody's rear harness melted through, basically the brake and tail wires became one. It behaved rather strangely.

Checked the wiring (as good as i could with a visual inspection) No signs of any melting. The connections seem solid. I noticed this morning, whether i engage or disengage the high beam lever, the dash high beam indicator remains on. Not sure if this has anything to do with the issue or not.

Wouldn't hurt to take a multimeter and test on continuity with the switch off at the bulb sockets. If you get continuity then that may indicate a wiring or switch fault that you haven't yet identified.

OK. I don't have any experience with a multimeter. I will see if I have any friends or family that can assist. Thank you for the advice, I really do appreciate it.

If no friends or family that know how to do this, there is always YouTube right? lol.

I think it is the LOW HID related. Install regular bulbs to test.

I think it is the LOW HID related. Install regular bulbs to test.

So I understand:

You think if I switch over from HID bulbs to regular the problem will be fixed?
Why would a regular bulb work, if the HID doesn't?
If the problem isn't in the wiring somewhere, wouldn't a HID bulb be functioning properly?

Just in case the above text comes across as a [email protected]#$ comment. I in no way mean it that way. I am genuinely wanting to know. I know texts some times have a different tone other than intended. I am not sure how to pose the question any other way.

HIDs are not just bulbs they include a ballast that plugs into the regular harness. HID Ballast are known to go haywire and have all kinds of issues as they age. HID ballast come in all kinds of quality. Did you install these or did they come with the truck. The stock bulb is a HB5 (?) which is a dual filament (both high/low) are part of the same bulb. Thus the ballast plug controls both hi/low beams.

I do not know if a stock bulb will fix the issue. But it is something that I would consider first as a possibility.

So i pulled the light connectors apart and noticed the connection points on the inside looked bent/smashed. I purchased new (truck side) connection and BINGO! that was the problem. The only weird thing now is, when the high beams are off, that's when the high beam dash indicator is on. The lights have 3 wires center being ground. I think it may be as simple as swapping the other 2 lights???

 

[gshaw1977]

i meant swapping the wires

Dumb question, but are the bulbs somehow installed 180 degrees off? If the sockets are/were mangled that could mean that the element for the high-beam is being engaged by the low-beam wire, and the opposite.
