Fogs not working
My fog lights haven't worked since I got my 02. Sometimes the light on the switch works, but not always. The switch (and surrounding areas) is also really, really hot. Any ideas on what's up? Thanks.

This is an issue of not enough information. Did you buy it new or used. Did you try replacing a fog light to see if it's the lights? Did you check the fuse or circuit to see if you have power threw the system?

In my 01 the fog and asr switches get hot when they're illuminated whether the fogs are on or not. Are both lights not working or just one?

Neither work. That's partially why I assumed it wasn't the bulbs, but the heat from the switches seemed abnormal to me; they get so hot that you can't touch them for more than a few seconds or it'll burn.
The lower the gauge wire you use, the less resistance and thus, less heat. A switch should not get hot be it in the home or auto. If you place a resistor (or load) in line of a wire then you will feel heat. Or, if you use lower gauge wire than you should, again, heat. A short also makes real nice heat as ground is a heck of a load. A switch simply "breaks" the flow of generally the "hot" lead. Perhaps you have corroded or exposed wires, too many things tapped into the one lead, who knows. It's time to do contortions and get upside down and look under the dash and feel the wires coming to the switch. The take away you need from this is that your dealing with DC and it's not troubleshooting an automobile, it's an electrical issue and the theory and process is the same for all, not just for cars. |

i don't care if it's an automobile, home or skyscraper, resistance to current creates heat.

yep, good idea. it could be a short or too many things hooked to the switch. also maybe the lights have been switched to a different style like an old hid that require lots of amps for the ballast's.
