In a fog over my fog lamps.

[thesoundguy]

On my 2000 Monaco Diplomat there are fog lamps mounted on the front grill. There's a switch on the dash to turn them. But, they do not turn on when you flip the switch. Also there is no 12 volts DC at the lamps when the switch is on.

I looked in the black fuse box in the compartment adjacent to the driver's seat, and there's no fuse marked "fog lamps". Also I checked the continuity on every fuse in the box and they all read good.

Anyone know if Monaco used a reserve spot for the lamps, and if so what number? There are several blank spots in the panel, and I'm thinking maybe the fuse blew and the PO didn't replace it.

Any other ideas where they might be fused from?

Help please.

Hello - mine are tied to the high beams.

Most OEM fog lights for automobiles won't work unless the low beam headlights are also on. Have you tried that?

Mine have been turned into driving lights and come on when the emergency brake is released. There might be a relay for them.

You have to have your headlights on and turned to Low beam for them to work.
I have a 1999 Diplomat and that is how they work from the factory.

Thanks for all your suggestions. I'll consider them all in the next few days.

Oldguy70,

I did find a relay for them in the fuse box but wasn't sure what it was tied to. When I get it back on level ground, running with full air pressure, I'll check that theory out.

I presently parked on very uneven pad with my tires chocked and my toad parked in front. Don't want to take out two vehicles in blow.

Thanks

If you know how to trouble shoot a relay you cab find if it has failed. First you need to see if you have current at the relay. Use the white wire on the relay at the top left corner in you fuse box for the ground on your test light. You should have power at one tab, you might need the key on. Next you just need to add current to the tab that pulls the relay coil in. White wires are usually ground so don't jumped to that on. Relays fail so it could be the relay.

This my seam a little obvious but sometimes those are the ones that get ya.
I have a 2002 Monaco Windsor. The fog lights worked intermittingly and then stopped all together. Went through the wiring, the fuses and surfed for hours seeking the answer. Turns out that the actual bulb assembly was deteriorating from a moisture breach. Once I cleaned the assembly, voila !! my next move is to remove the lenses and reseal everything.
Hope this helps
