No running headlights nor automatic headlights turn ON. Fuses all good and new headlights installed but nothing.
You may have a bad relay for the headlights. or a defective headlight switch.
A known to be good headlight will light if it is getting the correct voltage input. So either your headlights are faulty, or more likely the voltage isn’t reaching the headlight. Ask your shop to start probing the voltage at the headlight and work backwards towards the battery to figure out where in the circuit the voltage is being cut off. .
Headlights don’t work? Yep, new bulbs. No fix? My kids car had both brake lights out. And both bulbs were burned out. I guessed wrong.
