Fog light switch

[mjdwindshield]

Just curious about the fog light switch ,up or down to activate? When I do both ways ,both lights do not work. Just looking to know which is the on position so I can keep going back and forth diagnoising to a miniumum. Thanks

If the switch is installed correctly, pushing it down will turn-on the factory fog lights.

The headlamps have to be on low beam for the driving lights to light up.

Is the switch lighting up? When it does thats the "on" position.

Thanks for the info, I forgot which way the switched worked and that it lit. Nothing works so my first thing to look at is fuse if thats ok then there must be a relay somewhere right?

The switch could be shorted. The switch gets hot when the driving lamps are on, and no relay has been installed. In many cases these switches can be repaired if you know alittle about taking little things apart, and cleaning up contacts. Just avoid using the lamps too much, or install a relay. This has happened to most of us here.


Hey Eric I have 5 more posts than you.....nyaaaa

As Chris mentioned there is no relay in the factory stock circuit, which is why a lot of switches get melted when current draw runs up. I installed a relay and fuse to power the fogs and the switch is now insulated from the main current. The likely cause for the increased current, if you still have 55W bulbs, is corrosion between the bulb base and the contacts. Poor contact creates arching, which raises the current draw, which destroys the contacts, like the ones below. I made my own little metal clips out of light gauge sheetmetal to keep the contacts from arching...17 years and no issues. Good luck on yours.

Very nice job.
I'll send you my two back-ups for your upgrade design.

Are you coming to the Reunion?? If so, just bring them along and I will bring along what I need to make the clips rather than shipping your units.

Is the Borg Warner replacement switch still available?

[Otto Man]

Not to my knowledge. Man wouldn't it be nice if it was. I remember passing up a replacement back when they were available from BW.
Perhaps we might have a Borg Warner person here.

I've got an Allied Electric catalog here. I have looked a little for a suitable replacement in there, just there's ALOT of stuff and my eyes start to get crossed after awile....
