R33 Gtr Headlight Problem

[AzN]

My drivers side highbeam headlight isn't working. I've replaced the bulb and checked the fuse but it still doesn't work. Anyone have any ideas of what could be causing this?

Use a test light and check to see if power is getting to the bulb, if not follow it back through the circuit.

This is with R32 headlight switches so it might not apply to R33s:

If both highbeam and regular beam aren't working at the same time, then it's a common problem where the 12V power for the lights doesn't reach the headlights (battery->engine bay->cabin->headlight switch->engine bay->headlights). When you turn the knob it pushes springs which complete a electrical circuit, the springs will sag from wear and tear and won't complete the circuit.

If both high and low aren't working, but the highbeam flasher on the stalk does, then it's 100% a problem with the headlight switch.

There are 3 springs, 1 for both parkers, 1 for the left headlight (highbeam & normal) and 1 for the right headlight (highbeam and normal). You can stretch the springs out, but it's a temp fix.
