Headlight Trouble!! Need help please!

Hey everyone. My driver side headlight isn't working. Neither high or low beams. There must be some power because the shine very very dim. First i tried new bulbs. Then a brand new headlight assembly. Then I cleaned the headlight connector. Then I replaced the connector with a new one. Fuses are good. But could it even be a fuse, relay or switch when the passenger headlight works perfectly fine? Bad ground between fuse box and connector??? I sure hope somebody can help me figure this out. Thank you.

Sounds like a bad ground on the ground pack.

Get a voltage meter on the headlight connector to check your 12VDC.

I am getting 12v out of the pink wire. The other two are ground? Also I read the circuit goes to the dimmer switch. Was that meant to say multi function switch? Or is it possible my dimmer switch is bad?

i had a similar situation. i think one of the wires is suppose to be a switch wire. i ended up running a wire from the fuse box, 30 amp fuse the controlled the left side head light. shoved a bare wire under the part of the fuse closest to the headlight, and then ran that wire to the harness. its been working for years. a lot of times with random electric issues, its a bunch of trial and error. i wish i could remember the wire colors but its been since before my son was born, and he's 4 now, so at least that long.

also my guess as to why your getting a very dim light is from your DRL's.

Multifunction switch has been the culprit on a couple other problems... Not sure you can get to the contacts to clean them since the switch is inside the stick but maybe worth a shot to inspect or replace if you had access to a spare. The switch controls the ground side of power to headlight. Double check wiring from headlight to fuse block under hood.check this link...https://www.justanswer.com/pontiac/3...tch-cause.html
