There is a heat-sink resistor (has fins), approximatily 2" square under the dash just to the right of the steering column. It drops the voltage to 8 volts. People like to cut the wires to this device to disable the running lights. It is rare for this device to fail.
no
It would depend on what year full size Chevys you are working with.
Mostly likely: blown fuse or bad bulb
Our daytime running lights just stopped working on our 2007 Toyota rav4 bulbs???
light sensitive sells
check your fues
Taillights and daytime running lights not working may be caused by a blown fuse. The fuse can be found in the fuse box in the engine compartment.
Bulbs burned out or fuse and or relay popped
the daytime running lites go out when you put the trans in park. they also go out when you depress the parking brake. i would start looking there.
check fuse for the running light module.
As soon as the engine is started and the emergency / parking brake is released the daytime running lights are supposed to come on
Yes it does, but I'm working hard to remove this on my (Canadian edition) car
