If your fuse keeps blowing every time you pull the headlight switch, it usually means there’s a short somewhere in the headlight circuit. Basically, power is trying to go where it shouldn’t, and the fuse is doing its job to stop it before things get worse.
A few common culprits: frayed or pinched wires behind the headlight housing, corroded connectors, a faulty headlight switch, or even a bulb socket that's shorting out. Sometimes folks install aftermarket lights or wiring and something isn’t grounded right or properly fused.
If I were you, I'd start by checking the wiring and connectors at the headlights themselves. Look for melted insulation, exposed wires touching metal, or moisture inside the housings. If everything looks clean there, move toward the switch and fuse box.
That said, if you’ve already checked the basics and the fuse still blows, having the repair manual specific to your car makes a world of difference here. It’ll show you the exact wiring diagram, fuse location, switch function, and proper test procedures, so you’re not just guessing. Definitely worth having if you're planning to dig into it further.
