2006 Envoy XL low beam headlights will not come on at all. Went to Auto Zone and change the bulbs...still will not come on. Two weeks ago Pep Boys put in a new ignition stating the original one had sign of burning coil wire. Since then there is a little beep when I turn off ignition and now my low beam headlamps don't work. HELP

SOURCE: headlights alternate on and off left and right daytime/high beam

although the underhood relay panel is common, I'd check your headlamp bulbs first, these are cheaper than the fuse box. The daytime running lights work off the high beam circuit, thus, a blown highbeam bulb could be the culprit, the fusebox solution was more common on 2001 and up modles, although it's a definite possibility.

SOURCE: left low beam is out on my 2006 dodge ram 1500 4.7

I'd still vote for the bulb being bad. The high and low beams use two different filaments, so unless the bulb is physically broken, it is common for the low beam to be bad whilst the high beam is good.

That's why you see some people driving around with their high beams on -- they don't want to get stopped for a 'light out' citation..

When you take the bulb out to replace it, be sure to look at how it is mounted before removing. You don't want to accidently adjust your headling out of kilter.

good luck

SOURCE: One of my Headlight not working during low beam

replace both headlight bulbs
each bulb has two filiments inside the bad bulb has a burned out filiment but, they should be replaced as a pair
and, do not touch the glass with your fingers
the oil from your fingers can cause the bulb to fail

SOUNDS LIKE INTEGRATED POWER MODULE(UNDERHOOD FUSEBLOCK)IS DEFECTIVE..ALSO CHECK FOR CORRODED TERMINALS IN CONNECTORS ON FUSEBLOCK..HAVE SEEN THIS BEFORE AND NEW FUSEBLOCK WAS NEEDED AND REPAIRED PROBLEM

SOURCE: low beam headlights do not work

try the lights with the tilt wheel in the up position. If the low beam works then, a wire has pulled out of the connector on the mutipurpose switch inside the steering column. remove the covers behind the steering wheel on the column and there is a large multi wire plug with many wires. it should be obvious which wire has pulled out or broken.
