No Lights? (Page 2/4)

Okay I'll take a look here in a bit. On a side note though, I'm not quite sure what happened and I won't complain. But the indicators work now. Still no brake lights and like, uhhh. I'm not sure what the proper term for it is. Running lights?

I would suggest that you disconnect the battery in positive lead, pull the wires from the BJT and clean everything well and reattach the wires and hook up the battery.

It won't help solve your problem, but it will ensure good voltage transfer at that connector.

Eeeee. Wiring makes me nervous. Is there any tips on how to go about it?

It's not hard. Disconnect the battery.
Take the wires off of the BJT.
Clean the corrosion off of the wire ends and the terminal posts. (Sandpaper, wire brush etc)
(The two posts are connected together inside the terminal)
Hook everything back up.
Done.

Your headlights go up, do the bulbs turn on?
If they do, you may have a problem with the headlight switch.

Okay fair enough.
But yes the headlights go up, and turn on. But the headlights won't go back down. But it will turn off

If the headlights turn on, and don't go back down, I suspect the light switch AND/OR the module.

All of the other exterior lights also receive power from the light switch.

Fusible Links are very likely NOT your problem.

Link A to red wire is nearly everything in the car just including brake/turn/parking & other lights lights. IOW Almost Nothing will work including the engine if that link dies.
Link B to red/wht wire is only Headlights. So If HL Bulbs are On, Is Not a link.

Cleaning the Junction Box won't help this issue but often helps a lot of other wiring problems.
Clean then coat w/ silicone or permatex green label brake grease. Use a very thin film on the metal parts.

see https://web.archive.org/web...ocave/ecmwire_fl.htm
then see rest wiring section.

If all other front & rear parking lights are "dead" likely the HL Switch has failed for parking lights. Plus that also put HL Down.
Try pushing only the park side of switch first.

but also said no brake/turn light too may mean rear lights have more then "bad HL switch" like may have crap ground in back of car.
Pull the fixtures, find ground from any bulb socket then jump that wire to the metal & see if any brake/turn light works.
Push a pin in the back of a socket to hit the the metal end or the ground wire then ground that pin. If pierce the wire, coat the hole w/ tiny bit of "bulb grease" off a bulb or silicon to seal out water.

If some works other(s) not then can have iffy sockets or bulbs.

Troubleshooting can be a daunting task, and there are many ways to approach it.

Up to you how you get this resolved,

You could go replace a bunch of components and might get lucky.

You coul do some maintenance - electricity hates corrosion. Don't ignore the green on the connectors and mind your grounds. Plausible giving the synopsis you're providing thus far.

Break the system out into portions, the battery is the only source of power without the alternator running. You can work your way through the circuit and find the problem by going step by step.

Start at the head or the tail, that's up to you.

So I did take out the switch. It does look pretty burned. And one of the little "pin" things aren't fully reaching the part it needs to. So I did order a new one and hopefully that should fix my parking light and headlight situation.

When it comes down to the brake lights. I can't find the ground wire you guys are talking about. I get the feeling that one of the previous owners tried to do some rewiring before. Unless I'm just crazy.

What color is the ground. And where should I be tracing it back to? I'm so lost here...

I apologize as I'm still new to working on cars and this being my first car.

The 88 tail light harness grounds in the interior - passenger side top of console below the ECU.

Grounds are black, sometimes black/white.
