Thank you for that information.
May I get your VIN?
Lets start by diagnosing one circuit at a time.
Lets start with the headlights..
Is the truck equipped with daytime running lights?
Please accept my offer and call me
YUP! That will do it!!
Thank you for that information. I just pulled some diagrams for these circuits. This is normal as these fuses are only powered up on a diesel vehicle. They use this same set up in the 7.3 liter engine and these will have power with the key on in a diesel.
Check for power on fuse 11 and 9 under the hood with the headlights turned on (low beams)
If there is power in and out of the multifunction switch
I suspect there will not be.. as the multifunction switch is likley at fault.. unless it's been replaced?
Here is a wiring diagram of the low beams
That is the part on the left of the steering column that you push down and pull up to turn the blinkers on
Sounds good! Be sure to check for any blown fuses (especially fuse 13 in the battery junction box)
I am glad I can help!
