Euro Fog light replacement, No power to fog plugs Options

[Bucci]

Good evening gentlemen, I haven’t drilled down on any of the forms to find out the troubleshooting procedures.

1. I tested fog lights independently with 12 V source (working)
2. I hear the relay when I operate the highbeams.
3. All fuses appear to be good, I spun all the fuses under the dash for corrosion and connection.

My thought is the fog light switch may be bad, but it feels like all wires are connected. There is a green light that comes on when the switch is active

If anybody’s dealt with this lately. I need to check a Porsche manual to see what fuse is connected to the fog light circuit. I’m sure it’s one of the red ones.? I have brand new fuses in the glove box. I may replace them “all” but I did that 10 years ago. lol

Thanks,
Marc

Had the same issue. No fogs. Can hear the relay energize. Turns out the relay was bad. The contacts had oxidized and created a large resistance. Changed the relay and I was good to go.
