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.

Passenger headlight has a shortage in the wire. How do I know? The light bulb is not blown per auto mechanic, AutoZone, and by looking at the bulb myself; when I move the wire to the headlight the light...

You can fix it yourself you just need to find out where the shortage is. If its up close to the bulb then its not a big deal to change. Just go to an auto parts store and get a new headlight pigtail for it then splice it in. If its further up the harness it can be a little bit more difficult.

Lowbeam headlight on passenger side not working. Not bulb or fuse. Used test light and showing no power to bulb holder....?

Check your Light Relay. Your owners' manual should show you which relay it is. I believe GM splits the power to the left and right sides of the car in the Relay assembly. There should be a small box under the hood. You may just need to WD40 a corroded terminal and the Relay itself may be okay. Another thing you can try is clicking the Hazard switch several times. The Flash to Pass feature on the Turn Stalk works the high beam, but some of the headlight controls go through the Turn switch.

If all the above fail, try turning off the Autolamp feature and see if the Headlight switch will work on plain off and on like the old cars. It is good that you checked the wiring.

Changing the passenger side headlamp on altma

  1. Open the hood. Locate the two 10 mm coolant reservoir retaining bolts on the passenger side of the vehicle and then remove them using the ratchet and socket.
  2. Remove the 10 mm bracket retaining bolt using the ratchet and socket. Remove the bracket.
  3. Position the coolant reservoir out of the way to gain access to backside of the headlight assembly.
  4. Turn the large plastic headlight cover counterclockwise to remove it from the back of the headlight assembly. Remove the cover.
  5. Disconnect the wire harness clips from the headlight blades by pulling them off.
  6. Press in and then upward on the headlight retaining ring holding the headlight bulb in place. Remove the bulb.
  7. Align the new composite headlight into place without touching the glass bulb. Skin oils will greatly reduce and compromise the longevity of a halogen composite headlight.
  8. Refasten the retaining ring to secure the headlight into the headlight assembly. Plug the wire harness onto the blade of the headlight and test for function. Reassemble the remaining components by reversing the procedure.
Hope this helps. :)
