NO ONE CAN ANSWER THIS QUESTION

2004 Pontiac Grand Am SE

One headlight is dim, almost not even lit.
It is NOT the grounding wire, I spliced the wire and gave that headlight its own ground, no difference.
When I spliced the wire and it didn’t work, I hooked it back up to the original wire.
After I did that, the dim headlight switched sides??? When I hooked it back up, that headlight was bright and the other one went dim.
Changed bulbs, no difference.
There’s a buzzing coming from my auto headlight control relay. (Possibly the issue.)
Took the buzzing relay out, no difference.
So confused, no one has any advice HELP

Buzzing in relay=bad relay. No matter what happens after you remove it.
I had strange bu similar situation with son’s Eclipse. Not to mind twist too much, I simply spliced power wire from a working side harness. That was it. :woohoo: :side:

Before anybody can answer your question, you’ll first need to answer some questions yourself.

1) Is the headlight switch actually on? Even with the headlight switch off, you still get DRL’s.
2) If not, do the headlights go back to normal when you turn the headlight switch on?
3) Does the problem affect high beams, low beams, the DRL’s, or all of the above?
4) What color was that ground wire you bypassed? This one is particularly important because your hi & lo beams are all ground side switched meaning you’ve got two ground wires per headlight. If you’re grounding the high beam circuit with the switch in lo beam position, your bypass test was useless.

I have a wiring diagram printed up and applying what you’re describing to the diagram still points to a ground problem. Each headlight gets its own fused power wire. There’s not a lot of room to say that one power wire could affect the other with this problem. The auto control relay may not be the culprit either. When you’re dealing with bad grounds, electricity will try to back feed to find a good ground. That causes a lot of weird things to happen electrically.

I’d look at the ground on the other side.

The car sat for about 9 months, I recently started driving it again, tore into the wiring loom for the drivers side headlight, found a voltage drop from a split wire. Gonna solder in a new section of wire and problem solved.

Good to know.
NOW when my room mate’s 99 SE has that same problem, I can know where to start. Her car is nice looking but nothing but headaches.
