My fog lights don't work on either side. After trying different bulbs, I tested for power with a VOM - no power. Next, I swapped the fog light relay out with several others...still no power.

What are the next logical things to check? Do the fog light switches go bad?

Thanks.

Everything goes bad eventually. Did you check your grounds? And the fuse?

You are probably way ahead of me on this, but just to be sure...

The key has to be on and the headlights have to be on low beam.

Bet money that Dick is right, you have the high beams on. If you’re any good at electrical, rewire the fog lights to an independent switch and relay so you can operate them separately from your headlights. I use my foglights that way as daytime running lights. (IMG:style_emoticons/default/beerchug.gif)

Good points,you could check for voltage @ your fuseboard ,foglight relay pin #30 to at least isolate that as an issue then you know its further down the line,if that's ok it may be your switch but less likely.
Go well (IMG:style_emoticons/default/beerchug.gif) .

Oh man. I have a '73 and the fogs only turn on when my high beams are ON. I always thought that was stupid. Who uses their high beams in the fog?

I plan on re-wiring mine to provide voltage to the fog lamp relay so I can use them independantly as well.

JWest engineering has a kit to convert the fog lights to turn on without the headlamps being on at all.

Highly recommend this. I use the fogs as daytime running lights to help the idiots out there to see me coming.

IIRC, someone posted a "work around" using a jumper or switching legs on the headlamp switch so you didn't need the JWest kit. (IMG:style_emoticons/default/confused24.gif)

It sounds like they are set up to be used as driving lights...not fog lights. Did any 914s come with optional driving lights?

The euro market cars were driving lights. USA market cars, fog lights.

Done for safety reasons,in my country you can't have it anything different.
Would like the daylight setup but not an option for me bugger it.

Replaced my useless fogs with drivers from 914 Rubber. Work great. Also didn’t need JWest Kit, just moved one wire to operate independently with the switch.

Do your high beams work? If the one high beam that powers the fog light relay is burned out, the relay will never close and power the fogs.
