Yes does it need to be plugged in?

No, I was just asking because if it was unconnected it just reduces some of the variables at play which is a good thing. And I added something to my post for you to look at.

And the switch that you belived to be good was it from a coupe or vert, and did you see the switch itself connected to another car and it worked just fine or were you told this?

Assuming i did the jummper right i hooked a wire from the negative terminal and touched it to the ground in the connector going to the hl motor then i ran a wire from the wire reieveing voltage and touched it to both wires in the hl connector and nothing. There was voltage going through so idk... Any thing else i can try?

W/the plug disconnected it would work as follows and I apologize for leaving this part out. There are three wires you need to focus on. The Ground wire from the motor needs to be grounded so you did right on that. The White/Green wire of the front harness normally supplies constant voltage to the motor so that wire from the motor that would connect to this W/G also needs to have voltage as well, and I'm not sure you did this. And then voltage needs to be brought to the motor wire that normally connects to the R/Y wire. Is this what you did?

cupofresh

Yes that worked. I didnt run the wire that supplied constant voltage. So then does this mean it is the switch not switch the voltage?

cupofresh

Also, the switch was from a coupe, gsxl because i got the windshield wiper switch from the same guy and that switch works fine and he swore this switch worked just fine, seemed trust worthy and every other thing works on the switch. So are you thinkin it could be the switch now?

So it appears to be one of two issues. Either the R/Y wire and Red/Blue wires are comingling to the point where the voltage on one is being passed on to the other wire or there is something wrong at the switch and this assumes you have the correct switch. Did this switch come from a vert or coupe and have you seen the switch work on another or you were told it worked?

If you unplug the headlight harness from the switch and focus on which pin at the switch is for the R/Y wire and which is for the R/L wire to see if you get the same reading of voltage on both or not. If you do then the switch is the problem. If both pins read properly (one has voltage while the other doesn't) then the wiring would need to be looked at.

Reprise: If the plug to the switch is unplugged to test it the pin which receives the Red wire needs to have voltage jumped to it and w/the switch in the down position the pin that would connect to the R/Y wire would have voltage on it while the R/L pin would not.

So when i jump the solid red wire to the switch and the switch is in te down position there is no voltage on the r/y wire and when i read the r/l wire te voltage goes up an then fall all the way down. And its weird because i have those two switches that turn the headlights on all t time and i think those are the right ones and something is messed up with the wiring. But what are ur thoughts?

Hopefully u can see the video, so if i plug thr switch in about half way i can here some noise and the headlights start going up and down.

[so i checked and there is constant voltage on the solid red wire and the red/black wire, and when i touch the positive tester to the red/blue wire the voltage shoots up and then falls all the way down.

When you jump voltage to the pin that would be connected to the Red wire is this the only wire you have connected to the switch?

cupofresh

Yes. Do i need to jump the ground as well?

satch

That's a good idea but if it doesn't change anything then use a different ground source.

cupofresh

I got it! Idk what i did, i puulled both the red/white wire which is to the headlights and the red wite out of the connector and plugged them back in and now it works!? I think maybe something got caught in the red/white and shorted it out or something!? Idk! But now it works!

Btw, both switches that were turning the lights on and keeping them on work and the other 2 dont so i got ripped off by that guy, now i have an extra working headlight switch!

Remember in post #2 how I mentioned that the W/L wire connected to the R/W wire? Well, that wire provides a ground signal to the retractor relay besides sending a signal to the headlight relay and it appears that the signal on this wire was corrupted. Again, it's supposed to have a ground in the second position at the switch but voltage in the other positions. Anyway good for you.

You need to see if you can find a crack in the wire causing this problem. This wire also runs to the CPU (W/L) and this might be the problem if the wiring harness is not to blame.

cupofresh

Yeah, thanks, and I did look at your post #2 and started messing around with that stuff. I guess it is good for now. idk why it was doing that. It was just giving constant voltage to that r/w wire.

Thanks for all your help. Hopefully this thread could help someone else too. Sorry for taking you on the wild goose chase when your 2nd post was right, but I learned a lot from getting in there, since I have never used a multimeter or really worked with wires and such. Thanks again.

Okay, so update. My headlights have been working great, then all of a sudden, tonight the passenger decided to not go down. Now i have the wink thing going on. Its dark so I haven't done anything really, but I checked to make sure the motor didn't go out, so I put the headlights up and then manually lowered the passenger headlight, and it goes down and back up automatically.

So, what would cause only 1 headlight to work and the other to not? what wires am I looking for that would cause this?

I think,switch..again.(being an 89,but I could be wrong).
If you have the fuse in and manually maneuver the Headlights,then as soon as you put power to them then it just goes all Gaga again anyways.
If you need the lights UP,then take the "retractor motor" fuse out at the engine bay fuse block,put the lights up manually and they will stay.
Warning,do not put your hands near the headlights and slap that fuse back in.they will EAT your hands!!.Those motors are powerful!

cupofresh

But the switch works for the drivers headlight. and the passenger is now stuck in the up position. I know how to manually lower it, however, I am wondering what wiring should I be looking at, since earlier today the headlights were working fine, then I came out of work and turn them on, and as soon as I got home I shut the headlights off and the drivers went down and the other didn't. Could this be the switch? I figured if the switch went bad, then neither would work.

That is the thing..I am not sure if the Light motor has the Position sensor in it to tell it that it is open or closed.I am assuming so.
Then again I recall something about the Relay being in the Headlight switch on s5's..
I can only,for now,suggest the "manual UP/Fuse out" thing..and then someone else can actually give you Solid info.

How many wires connect to the passenger headlight? Answer: four of them. You already know by now that Black is the ground, W/G is constant voltage and the other two wires should have voltage on one but not the other depending on whether you want the light up or down, and this has been gone over at least once if not more in this thread. Things have not changed since then. You know how to unconnect the headlight and check it from there.
