I run with the fog lights on generally at night. If I turn the brights on, then back off, the fogs go off with the brights, but do not come back on when I turn off the brights. If I push in the switch and pull it back out, they come back on...until the brights.

Any idea which relay or what I should start doing to track this down?

Relay going bad? Switch it with another relay and see if that cures it. On my C4S I had it jumpered where the fogs stayed on with the high beams. To do that you need to remove relay 34 and jump pins 3 and 5.

I'll try that. Electrically, I'm rather Amish. Thanks for being specific.

I, personally, am very much against running the fog lights under any circumstances. Unless there is dense enough fog.

Regardless of when I choose to use them, I want them to work

I'll try to check mine if I have a chance tomorrow. It might just be normal operation?

That is the way it is wired by the factory!

JPS

That can't be right (no offense). Why have a hard switch / **** then? What is the value in having lights that keep turning off?

...Well stated

Any update on others' operation?

If the fog lights are on with the main lights, they turn off when you switch the high beams on. As soon as you switch the high beams off the fog lights turn on again. That's SOP for ALL cars, and our Porsches are no different.

So it isn't standard that mine don't come back on. I'll check out the relay. Thx.

This is the way mine work (I just checked).....

JPS

Thx.

JPS, sorry for the delay, I was on the road for a few days.

Checked mine, the fogs (driving lights) do come back on when main lights are switched from high beams back to low beams. So my thought is that the relay could just be getting stuck? I'd see which relay feeds the driving lights and whack it a few times before trying the sequence again.
