You probably have a bad ground on your "dim" light.
check that both bulbs are the same and the connectors are on the same - if they are the same check ground connection
my head lights wont come on ,,all other lights work ,,no head lights
yes, if truck has day running lights, the low beams are on at all times, when head lights are turned on by the switch, the voltage is increased on low beams to a full 12 volts on low beam, when switched to high beam, all four are on.
no They do make kits to where when you turn your high beams on all 4 lights come on.
I found this on my 1997 Silverado and found the connection from the wiring harness to the back OS the switch itself was loose, I could wigle it arouns and make the lights come back on.
You need to replace the bulb in your lights. The dim lights and bright lights have different bulbs.
No, the fog lights have a switch.No, the fog lights have a switch.
The lights are automatic for your daytime running lights AND your regular head lights. There is a light sensor on your dash that knows when it get dark. When it's dark your headlights will automatically come on, daytime lights turn off and your dashboard lights will dim as a result, since you no longer need them to be that bright when it's dark. As far as the parking brake, it triggers your daytime lights to turn off, so when you disengage your parking brake, they will turn on for normal driving. All of this is a good thing because you never have to worry about turning your on/off...ever.
If you are pulling it forward to make the light come on....try pushing outward...
the twisty thing that turns your lights on and off.. PULL on it. they should come on.

The heater might blow cold air in a 2000 Silverado because the thermostat is sticking and not changing from cold to heat. The thermostat is usually located in a hose that leads from the radiator to the motor.
