Driver Side low beam light not working - replaced lamp & checked fuse

I have a 2006 Nissan Altima.

The Driver Side headlight went out. High beam works fine but not the low beam.

Initially thought the light was burnt out so I replaced it with a new one… Next I checked the fuse box. I replaced both the 15 and the 10 amp fuses for the H/L Hi/L and and H/L Hi/R. Still nothing.

I’m guessing it at this point it is a wiring issue, however if others have tips on how to troubleshoot and narrow this down quickly, I would be very appreciative! HELP!

In advance, thanks

Hi,

If you've got a DMM (digital multimeter) check if there is voltage appearing at the bulb connector when you turn on the low beam switch.

If voltage is there, then use the Ohmmeter function in the meter to check that there is a good earth connection on the other connector to the bulb. If the voltage is there and the earth connection is good (0 Ohms) then perhaps the connector may be faulty -corroded.

If there is no voltage appearing at the connector, swap the high beam and low beam relays found in the engine compartment fuse box and see if it now works. (ensure that the headlight switch is off when you swap relays to prevent sparks etc when plugging in relays)

Hi @ Al Mccloud

Here’s an image of the layout of the engine bay fuse bock for a 2006 Nissan Altima showing the headlamp relays.

Are the headlight relays in the fuse box undre the hood?

I looked in the fuse box and i noticed that they're a couple relays down in the box under the fuses.

Well, i never saw a reply from the original poster about this issue. But for future reference i have a possible solution. On a 2001 Quest the power flows from the battery to two 15a fuses. one for the right and one for the left side headlights. the fuses control both the high and low beam circuits. check to see if they are good. Also do a voltage reading to see if power is available. after that the power flows through a headlight control unit. im not sure the purpose of this unit since the headlight circuit is pretty basic. After that they flow seperately to each headlight, one wire for low and one for high . do a voltage reading at the headlight bulb connector. the center wire is ground. black wire with white rings. . and finally got to 3 grounds. redundant grounds are not a bad thing. these 3 grounds are all interconnected and are common to all your exterior lighting. so if one headlight is out and not the other, or both headlights are out and not the marker/parking lights, its not the grounds. use this to get the basic picture of the circuit health. if you use these points and your headlight does not work, go to your headlight control unit. test circuit power intput at the pins that feed into the module from the 15a fuses. this will establish if power is going in. and then again on the output side feeding to the headlights. this will establish if power is being lost or diminished in the module assembly. you should find the discrepancy there. you can order this module online. in 2019 they seemed to be going for about 30-40 dollars. or… go to the junk yard, pull one from a vehicle there. cheaper and it help you to learn how to take them out if you have a pick your own part type place in your area. now, if after all this you still have no definitive answer, you will need to start opening up wiring harnesses and digging through wires to look for breaks. Good luck

Hi @Pam Baker

Here’s an image of the relevant section from the 2005-2006 Nissan Altima Service and repair manual show how to check for no low headlight, one side only.
