Defective PW motor, short in the wiring or the switch.
you need to replace the fuse for the headlights.
If the headlight fuses on a 2002 Infiniti Q45 keep blowing, it may indicate a short circuit or overload in the headlight wiring or components. Potential causes include damaged wiring, corroded connectors, faulty headlight bulbs, or issues with the headlight switch. It's important to inspect the wiring harness and connections for any signs of wear or damage. If the problem persists, consulting a professional mechanic for a thorough diagnosis is recommended.
Short in the wiring is the most likely cause.
most likely.
Short in the wiring or the device it powers.
A short to ground in the positive side of the headlight circuit. Most likely by a failed headlight switch. Ford is notorious for faulty healdight switches.
If it blows when cranking the starter has failed.
It might be because of moisture. Mine would go out every time it rained. I had my mechanic put a new silicon seal on the headlights and that solved it for me.
Are you touching the bulb with your oily fingers b/c once you do that, the bulb gets hot and pops on its own.
no i did not replace head light switch
