Measured the fuse in the dash fuse panel with the headlight switch on, voltage at both fuse terminal tops. Measured voltage at the bulb connector, only .7v there. Is there a relay somewhere for the headlights? I know there's the bcm relay box by the battery, does this manage headlight power as well?
First post here for me, but I've been viewing for about a year now. Thanks in advance for the assistance and thanks a ton for all the information here I've used this year!
I am hoping you are using a ground separate from the wire at the headlight bulb connector? Check Illumination Control Module (ICM) pins 3 and 5 for the 12v (system voltage) heading to the bulbs when set for headlights to be on. If pin 3 is not hot and pin 5 is hot, you may need a new or replacement ICM module. If both pins 3 and 5 are hot, you have an open in the wiring harness from output pin 3 to the headlight connector. Hope this helps!
