Just pick up another Fc after almost 10 yrs. I was about to put on the jdm fog lights housing i had for previus fc but found out the fog light won't work. Try the fuse and light bulb still no luck. My next step is changing the fog light switch but I'm wondering if it might be another issue.

Anyone ever deal with this before?

 

Should be rather simple to figure out. The Fog Lights Relay is located in front of and to the side of the radiator along w/the Headlight Relay and Dimmer Relay. The relay you are looking for has four wires. Red/Yellow should have constant voltage and is powered by the Fog Light fuse. Black is the ground. Red/White has power w/the lights on and the Fog Light Switch depressed. And Red/Black, which carries voltage to the Fog Lights, has voltage when R/W has voltage. So when you turn on the Headlight Switch, voltage is sent to the Fog Light Switch in the car. When you press the button the voltage passes on to the R/W wire. This voltage then winds up at the relay. The relay then passes the voltage via R/B to the Fog Lights.
