Low beam light on 2005 yukon not working.

SOURCE: Headlights

I READ ONLINE THAT THERE WAS A RECALL ON THIS YEAR AND MAKE, CHECK WITH TOYOTA WEB SITES TO RECTIFY YOUR PROBLEM

SOURCE: no low beams bulbs are ok fuses look good

There may be a relay that operates the low beam lights, check the owners manual to see if there is a relay, you should be able to hear it go "click" if there is one.

SOURCE: fog lights and high beams work, but not the low beams

most likely the hi lo switch

SOURCE: Audi A4 2002 Low beams & Right front turn signal stopped working

but on 2002 A4, F20 and F21 are empty! Does anyone has an idea where the headlight fuses located?

SOURCE: I have a 2008 f250.

I am sure that a 12 Volt bulb means it needs 12 Volts. Since you changed the bulb to the other side, why not check the voltage in the working side and see what it reads?

Sometimes the turnstalk can interfere with the lighting. Try pushing the Hazard switch several times and see if the headlights straighten out. I read that too much goes through the turnstalk and that using the Hazards can derail a contact inside the stalk.

If this does not help, you may need a headlight relay in the powerbox. One contact may be dirty or burned down for the wire it feeds. Unless you have a single wire feeding both low beams to the headlights, I would bet the left and right side come out directly through the relay.
