Hello,I will be glad to try and assist you with this,Welcome to Just Answer.
Check the big 50 amp lighting fuse in your under hood fuse block and make sure it isn't blown.I believe its either fuse 6 or fuse 8.
This should be the only fuse that powers these lamps.The fuse power runs through the headlamp switch and the dimmer switch then to the headlamps.
Chances are this fuse could be blown.
Let me know if you need anything else,Thanks Pete!
Can you disconnect the wiring connector at one of your headlamps and test for power on the tan wire terminal B at the headlamp assembly.Test for voltage here with the headlamp switch on and the multimeter hooked to a good ground point.You can test this at either headlamp.
Then test for ground at terminal A at the headlamp connector with your multimeter hooked up to battery voltage at the battery.You should have ground here even with the key off.You can also test this on either headlamp.
Let me know and we can go from there,Thanks Pete!
I dont have a schematic I can list here due to copyright issues but I can try and walk you through this if you want.Or you can try AlldataDIY online to see what they would charge for the schematic.
What was the fuse labeled that was blown.
Let me know,Thanks Pete!
