    i thought the right side low beam was burnt out. so i put it in the left side low beam light. found out that it worked, just not in the right side light. i checked the 15 amp fuses, they were not blown.

    i am at a stand still!

    hi , you do have a 10 amp fuse for right and a 10 amp fuse for left low
    beams , with or without HID headlights , they will be under the right (
    passenger ) side of the hood in a fuse block . they should be labeled BML & BMR , also there are 2 seperate ballest's if they are the HID type , check for those 10 amp fuses first .

Why did you pull them out? I suspect that the right one did not get seated properly or there is corrosion in the connection - is the housing watertight? I don't think it's a relay since neither would work. Could be a bad ground connection on that side.

What would cause the low beam headlight not to work when all other lights work?


If you have standard halogen bulbs:

  1. Burned out light bulb; or
  2. Fried wires between the dashboard wiring harness and the headlight bulb connectors; or
  3. Fried headlight bulb connectors.
If you have HEI emitters:
  • Failed ballast.

No power to right side (PS) headlight low beam plug socket, new bulb, fuse is good. High beam works, blinker works, park light works. just no low beam and doesn't register any voltage on volt meter.


check low beam fuse when switched on if it has voltage registering across the fuse ,if there is voltage across the low beam RHS fuse then it is possibly a pinched wire from the headlight running back towards inside of the car

I need to replace low beam head light lamp, right side. 2002 dts


Pop the hood, remove the plastic cover over the radiator, remove 3 screws holding headlight assembly, yank forward, remove plastic plate on the back of the assembly, carefully twist and remove old bulb, replace new one the same way. Remember to change both headlights (even if the other one still works!) Changing only one will cause the older one to burn out quickly and besides, you'll have different brightness levels. Hope that helps.

Sounds like you need a bulb,the daytime running lights send power to the high beam wire so they look like low beam lights are on but really they are high beam lights running on low voltage.

2003 Seville STS low beam headlights don't work


ya its is prolly the bulbs, open your hood. look behind your headlamps, some have covers for the low beam and high beam. if there are covers turn on your high beams so you will know which bulb is your lowbeam. if you can unplug them. after cover is removed and you can acces the bulbs. they either twist out, lefty lossey. or they have little metal retainers that you have to move a certian way before you can swing the retainer out. its like a door you just have to unhook the proper side of retainer and the other side will be hinged. use a flash light and look at it close. good luck
