Question about 2001 Chevrolet Silverado 1500
My high and low lights don't work everything else works even the fog lights. I checked the relay and that is fine. Any ideas?
Their is a switch on your emergency brake pedal that deactivates the lights, when applied. Maybe loose

Check the fuses under the hood...chances are it's one of them....there's not much left to check after that....check the fuses inside the car as well...it might be the high beam switch is bad that switches the low beams to high beams inside the car.

SOURCE: headlights wont work
Well...lets start with the obvious. Check fuses and NEVER piggyback any stereo or security stuff into their fuses...you dont want the lights to shut down during a night drive!!
Check under the hood for a relay center...also has some fuses there as well.
The Daytime Running Lamps are a "straight through wiring configuration". Doubt it even goes through a headlight switch at all.
But the regular lights do.
Unless you've worked on the front of the car and forgot to plug the headlights back in, do this...
Turn the light switch on...looking at the instrument cluster , can you make the high-beam-indicator light come on?
As you rotate the headlight switch knob...does the instrument panel lights brighten or dim? You probably have a faulty headlight switch...auto stores have them...they simply plug in.

This may be the start of a worse problem that the Impala eventually developes. The Body Control Module has a design flaw along with the Passlock anti-theft system. You may get away with just replacing the BCM for now. It needs to be reprogrammed at the dealer and the car will not start if you replace the BCM without reprogramming it. I would also recommend against replacing it with a remanufactured one. Repair cost is going to be around $500 at the dealer.
If the Passlock system is also at fault, add another $500 for a new ignition switch and cylinder. If you haven't experienced random starting problems yet, they are coming soon. When you turn the key, nothing happens. I thought my 2002 Impala may have been immune to these problems that I've heard about constantly, however, at 90,000 miles, it became "possessed". The symptoms started slowly and got worse. Beside the interior lights flashing like strobs in the middle of the night (while the car was not running), the headlights would occasionally click off and on a few times while I was driving at night.
The relay switch you hear clicking is the Battery Rundown Protection relay. I'm suprised your battery hasn't drained to the point where the car will not start in the morning.

Day time running lights run low voltage to the high beam bulbs so it sounds to me like you need two new bulbs or you need to check the fuses and see if any need replaceing.
