Headlights WON'T listen

More info on what has been done wiring-wise please (Cliff notes are good). If you start blowing bulbs (which can take out switches in the process), how is your car's voltage. An alternator voltage regulator on the edge of dropping a duece can allow high system voltage (15+ volts). This can blow out bulbs.

You have a fog light relay socket in the underhood fuse box - I suppose you could have used that if you had desired.

What is the source for the fog lights being able to turn on (what's the power source to your fog light switch)?

It's not uncommon for the headlight switch connector (not the switch necessarily, but the plastic connector that the switch plugs into) to overheat and cause issues.

One question for the 94-95 guys: On foxes, there's a thermal switch in the headlight switch (it's like the thermal switch on your hairdryer). Do 94-95's have one as well? On a fox, flickering headlights would mean the circuit is overdrawn and the switch is tripping. After the lights are off for a bit and the thermal switch cools and the contacts reconnect, the lights come back on.

Good luck.

How did you wire the relay exactly? How did you manage to run the low and high beams to the relay (terminal 86 most likely) without having backfeed issues? Did you use a diode? Otherwise, I can see an issue where anytime either lows or highs are on, you're actually energizing both lows and highs at once. That could heat things up a bit.

For simplicity, I'd have wired the fogs up to the parking lights (if that's legal in your locale - it is NOT in many places. If not, a switch for the fogs is needed). Wiring it to the parking lights means that anytime the parking lights are on (including with lows and highs), the fogs are on.

And otherwise, the relay should only have one wire going to the battery (the common terminal, normally 30).

Am I way off base with how it was wired up?

Good luck.

Has someone on that site used that configuration? From what I can see, that's horrible. You can see that the wire for 86 is now connecting high and low beams (since both are connected together via that wire).

There should have been blocking diodes installed with that kind of set-up. Can you kinda see what I mean? WHen the lows beams are on, the power goes to the 86 wire, but it also goes into the high beam wiring. That's what I was afraid of and I dont see how this can work when wired as it is.

MHO. Good luck.

I'm not saying the lights wont work.

Let me ask: So you only have either high or low beams on, when you turn on the headlights? Both should be on if it's wired up like that. And if both highs and lows are on simultaneously, that can cause just the issue your having.

Good luck.

Have you checked your headlight switch? I'd bet that you ruined it or the connector that plugs into it when you wired it up like this. When you have the lights on low, you are pulling all the current for both the lows and the highs through the switch. (In just normal use) it is very common for our cars to have the switch go bad, and take out (meaning melt) the connector that plugs into it, thus causing intermittent connection and flickering. Disconnect the shorted low-to-high wiring to the relay, check the switch, and wire it to the parking light or low beam circuit.
