Unhappy headlights out... where to look

Afternoon,

Another day, another problem it seems... but it's ok.. soon all the bugs will be gone...i hope!

This problem just happened 2 days ago...

The headlight switch has 3 positions... !) OFF, 2) parking and 3) headlight+parking.

1) OFF works
2) Parking works
3) it becomes all OFF again

I opened the casing around the steering column, pulled the cable out from the switch and disconnected it.
I put a voltmeter to the switch and tested the switch and I get voltage across position 2 & 3, so the switch is good.

So I need to somehow go down the wiring. Anyone know where the next "junction" to troubleshoot is?

Or any ideas on where to look?

Thanks,

~Ji

I assume you have tried the fuse for the main & full beam as they are on a separate fuse from the side(parking) lights, or the headlamp relay.

I have seen the switch go short cct and blow the headlamp fuses.

have fun..

Pull the switch out and look at the 3 copper connections inside. your 3rd copper hit point might be burned out. Its a common problem. Happen on mine 4 years ago. You can buy a new one or fix the connection.

Edit: oops! just read that you tested voltage across position 2 & 3 and it was good.

Switch is hosed. Under the high load of the lights they go bad.

Only other possibilities are the fuse or having both go out at once (my LWB did this and I was like WTF for a good hour until I figured it out the "Ron good" way ie replace parts until it works again).

Does the inside of your switch look like this?

My Series had this problem. It was the hi-low beam switch that went out. I am not sure this applies to the Defender class trucks.

I would buy a new switch after looking at the fuse first of course. Mine did the same thing and the switch looked good but had melted just enough to not make contact when the switch was moved to the 3rd position.
