2001 Chevrolet Tahoe: Headlights not coming ON?

All other lights work,but both low beam and High beam lights are not working.

There are many possibilities that can cause this problem.
A faulty head light controlling fuse or faulty head light controlling relay.Faulty head light switch or loose/ short wiring.

But Most commonly this is caused by a faulty multifunction switch, At the headlamp
dimmer switch, ground the Purple wire at pin E11 and see if headlights now come
on. Do the same thing at Yellow wire at pin E12 and see if low beams
now come on if so then replace the switch.
For more understanding i will say,Check the head light dimmer switch that is a combo with the blinkers,that is the multifunction switch.

This details will help.
