Having problems with your 2000 Chevrolet Blazer ?
Daytime running lights work but go out when I turn headlights on. Ruled out headlight switch, bulbs, fuses, relay, ground, and DRL module. 98 silverado 1500 has no high beams. headlights work with parking lights but not when headlight switch is turned on. Switch was the first thing I replaced.
If you have daytime running lights but when you turn on your regular headlight on they do not come on. Take the bottom of your steering column off (Two Small Screws) and look at the back of your turn/dimmer switch make sure that the light blue wire is connected. The wires will break off after years of raising and lowering your steering column.
If your car has fog lights this is the way they are supposed to work. the fog lights and DRL lights are the same light.
