87 vert fogs not working

Thats the nomenclature they use for the switch on the turn signal stalk.

the WHAT???? LOL

What I am thinking is the headlight switch and fog light switch are sharing the same ciricuit or power supply for some strange reason or perhaps thsi is what it is supposed to be. the low beams come on like clockwork every time with the fog light pressed in. but they come on at about half intensity. Turn off the fog switch lights go out.

ok, I looked a wiring diagram/schematics from Bentley, and it shows there is a high beam dimmer relay or switch located somewhere. Not to be confused with the dimmer on the headlight switch for the interior. I didn't test the fogs yet as suggested but I am wondering where it is and what this switch does? I threw some pics up. The part is in the left of both diagrams

Yikes, can't blame you there. I'm too much of a wuss to work on my car because its a nice warm 20deg outside.

Hmm, that's a new one.

First item is since the dash indicator works, there's power at least at the fuse and that whole circuit is not being pulled to ground.

If you happen to have a meter handy, pull the drivers side fog light apart (leave the bulb connected). With the green light on, and the meter grounded somewhere on the chassis separate from the fog light, bracket, bumper, etc. check for voltage at the positive lead coming in the housing, and the metal housing itself.

So I find out my car has an integrated low beam check system that is integrated into the circuit board under the fuse box. Every time I put my lows on the light in the check panel comes on. Lights work fine. I can live with this.
However; since I installed the factory fog lights and plugged them into the pre-wired plugs something odd happens.

when I put the fogs on the green light in the dash comes on. but no fog lights. when I put the parking lights on and put the fogs on the low beams come on dim. But still no fogs.

I checked fuses; I checked relays. Both my low and fog light relays are the light blue ones. I swapped them to see maybe it was the relay.

any help would be appreciated. Thx.
