Thought I'd update this thread, I replaced the headlight module with a known good one and it did not resolve the issue, spewing.

It has to be something to do with the wiring behind the stereo to the small lights that illuminate the air intake / fan operation.... oh well.

i had the same problem last week. it was just some loose wires on the black relay down near the battery. i had to resolder them where they go into the relay.

after you replaced the switch did you try winding them down manually with the battery still turned on. when i did mine i did that with the switch in both positions (couldnt remember what was up or down). the lights popped down and it was all good.

I didn't try that, sounds a bit weird that that might fix it, but I'm willing to try anything.

How do you manually wind them down? do you have to take the grill or bar off to get to the motors?

Silly question but I guess you've tried lossening off the threaded adjusting arm on the side and then give it some turns to lengthen it?

Not sure I know what you mean gerry, but once i take a look i'm sure it will make sense.

The thing is, when I reset the ECU by leaving the power off for around 30 seconds the lights go down perfectly.

Its a wierd one, the overly compliated electronics controling the h/lights give me the shits

Yep - found the relay - swapped it - same thing.

But found that when I took the relay out then put it back the lights went down - so wired a switch in to cut power to the relay - now all good - fixed - I just got two switches in the cabin to contend with.

Check the headlight diode beside the headlamp sensing relay near the battery.

Have you managed to download the s12 workshop manual off the net? should be a link in pinned info. The page that will help to identify the diode is EL-194
It is a small Green? rectangle block beside the headlamp sensing relay which is situated inbetween the battery and the headlamp. Also has on the side of it the symbol for a diode which is an arrow pointing at a vertical line.
