Another 180SX pop up headlight issue post...
THRILLHO 22 Sep 2017
The motors appear to be working as when I wind them manually down and press the headlight button, they flip up straight away no problem.
However, if they're wound down and I turn the headlight stalk, the lights will come on but headlights won't pop up.
Have read through a bunch of posts previous to this and have tried most things
- Relays - heard them all click when applying power directly to them, switched the 3 on the right relay box in all arrangements and power is getting through
- Checked power out from male end of connector going from a engine to headlights themselves and got 12V readings. (Did this a couple of weeks ago but I'm pretty sure we checked this)
- Headlight stalk - removed and opened up fully, cleaned contacts (even though they weren't really dirty or scored at all)
- Headlamp timer - pulled out, opened up and checked inside. Didn't do any direct power tests to this as it seemed in brand new condition and there were so many outputs
- Checked all fuses
- Pressed the headlight button many times out of frustration
Any more ideas? Would I go to look at all the wiring now?

Interesting.. based on that I looked them up and found
180SX stalk: https://www.efisolut...tor-stalk-180sx
Silvia stalk: https://www.efisolut...cator-stalk-s13
But then comparing to videos I took when dismantling it, I see that I have that extra cord going out of mine.
However, I do remember when I was undoing stuff around the steering wheel that there was another plug that wasn't connected to anything.. maybe I'll take it apart again and try put the headlight stalk foam covered plug into that other one and see what happens

The headlight popup switch might not be working properly, or might not be plugged in correctly. In that case, there are 2 contacts on the plug that need to be connected in order for the lights to operate normally. I don't remember which, but a search should tell you. I had to bridge them when i repurposed that switch. Lights would go up and stay up until I put a paperclip across them, same as your problem.
Tldr; your issue entirely relates to the button on the right of the dash. Plug it in or stick some wire between the pins that normally stay closed. It probably just hasn't been plugged in though.

Which contacts would I have to cross? I didn't really understand the wiring diagram

I'm pretty sure I just ran a continuity test with a multimeter on mine, then bridged whatever two pins were connected when the switch was off. You could do the same and test the switch on/off, or take a guess and bridge what you think is right using a paper clip (namely the top row, far left, 1st and 2nd on the same row, looking at that picture with the locking tab at the top), or open up that switch and clean all the contacts. Chances are the contact connecting to the 2nd pin just needs a scuff up with some sandpaper.
