Ok my headlights stoped working all of a sudden. I checked the fuse and the light boulbs but they are OK. I though they might not be grounded properly BUT the weird thing is both of the headlight dont work! Now thats weird to me. Anyone had a similar problem? And is the headlight wiring in serial since both of them are not working?

Thanx in advance.

The relay is the fist thing that comes to mind.

So they don't go up and the lights don't come on? Maybe your switch went. Does the switch that makes them come up without the lights coming on work, or no?

Icemark

can you flash to pass???

menace

Sorry no the light pop up but they dont come on....

Ice mark im not sure what you mean...


also highbeams dont seem to be working.

Ok, so the motors still work, but the lights won't come on? Hmm..is there a fuse inside the car for that Icemark?

menace

Yesh i checked that the fuse is fine. Its the 15Amp one on the top row in the corner. I chaecked every single fuse :LOL:

Icemark

Flash to pass is when you pull the switch back and the headlights flash through the opening in the bumper

Ok i tested the wires going TO the headlight and im geting 12 volts ON ALL three wires wht could this mean? Bung Relay?

Icemark

The switch throws ground on the on Red/White wire, it should be resting at 12V+

when you ground the red/white wire the headlights should come on. The red/white is in both the 10 pin and 14 pin plugs at the light switch.

To check the switch, when it is on to the headlight on position, the red/white will have ground on it.

If the lights don't light when you ground that wire, then check the head light relay.

At the headlight relay, when the white/blue is grounded, the red/green will have 12V+ on it. If it doesn't then you have a bad 30 amp underhood fuse or bad headlight relay.

and you never did answer if the flash to pass works???

menace

Ok im not 100% sure what you just as im tired said but my dads a electrical engeneer so all Good

No the flash to pass does not work.

PS im getting 12v whith all of the headlight wires when the switch is in the off position :S Sorry i didnt mention this earlier.

menace

oi icemark not to bug you more but can you extrapolate on what i had said, in my previous post

Thanx in advance.

That's only on US models. Menace's is a Japanese car, so the headlights pop up when you flash them.

Menace, if they're popping up but not turning on it could be the headlight relay or the 30A headlight fuse, both of which are under the bonnet. If you don't have a wiring diagram, get one. It makes this sort of troubleshooting much easier.

Icemark

Ah good catch NZ, I am sure you must think we americans think the world should be our way...

anyway to describe more,

The headlight switch, switchs 12 Volts for the parking/running lights, and the dash lights, but switchs a earth or ground to activate the relay for the head lights.

So in my above post, I described how to test both the relay and the switch.

But like NZ, I think it's more related to the under hood/under bonnet headlamp fuse, but I gave you how to test the switch and relay anyway.

I'll figure out how to do that some day.

Naa i alredy tested the fuses they are fine. Both the in cabin AND the enginebayone.


Also i have both the FSM and the haynes manual. SO im not short in wiring diagrams. But what i need IS real life wire diagram. :S As in where it goes on the car.

menace

PS, what the hell is a dimmer relay? Anything i need to worry about?

HAILERS

Headlights can be found in the front of the car.

The switch is near your left hand when you drive. Its that round ****.

The 1987 FSM has the wiring diagrams plus on the back of each wiring diagram page, it has a picture of the car and where each item goes. As in where the ground wire is for each light assy. Near the trail coil assy, if I remember right.

If the dimmer relay contact went bad....might make it difficult for the circuit to be made to the lights.

How come everyone mentions the bonnet but never the turtle? You can get your spanners out and really go to town on some items in the turtle. Strut tower assy's and dampers to be worked on back there. One of my first turtles was on a XK-140MC. yEEEEEHAAAA.
