For some reason Sometimes my Drivers side headlight comes on and sometimes it doesnt. When it doesnt come on it doesnt. And turning the switch ON or OFF doesnt make it come on.. Its very random. COuld this be the Bulb or The Ballast

thanx

Could be any number of electronics from the switch to the relays to loose wiring connections, even a bad ballast. A bulb typically won't be hit or miss as such so I'd look in other directions...unfortunately.


EDIT: I'd focus on the connections to the ballast and between the ballast and the light. Since it focuses on one headlight and not the other, the switch/relay probably isn't your problem.

 

does it flicker when you try to turn them on??

on my 04 - the dealership had my car in five times and finally changed the ballest.

 

Since your car was hit on the same side, you need to pay close attention to all the wiring. Including the ground next to the hood prop rod.

swap bulbs side to side to see if the problem moves with the bulb. If it stays the same, it's the ballast. If the problem moves with the bulb, the bulb is bad.

 

IT started before I was hit.

 

That same advice still applies.

 

does the light flicker??

 

No sir it doesnt. ITs just either on or off. It worked fine last night , But tonight could be a differant story.

 

i had the same problem on my 04 - it would work then it wouldn't work - was the ballest - i would ask a buddy to turn the lights on and look closely - you cant see it flickering from inside the car

it's an expensive part that was on "critical back order" from Japan when i needed one - so my dealership just took one of an 05 that was on the lot

 

NIce. Well my dealer is a dumbass. I would go to the dealer but they said they cant do anything or diagnose anything with anything aftermarket on there.
