So you hit your Porsche fog light switch and...nada. Nothing happens. When you start thinking about a trip to the mechanic to figure out what's going on, dollar signs begin to swirl in your head. But it doesn't have to be that way. Your Porsche fog light setup is relatively simple to diagnose. Most Porsche fog light issues stem from a bad Porsche fog light bulb, actually. What causes the Porsche fog light bulb to burn out is another question. Like all filament bulbs, the Porsche fog light bulb is susceptible to moisture damage. If water gets into the Porsche fog light housing, chances are the bulb will blow pretty quickly. So to fix your Porsche fog light, you need to replace the Porsche fog light bulb and fix any cracks in the Porsche fog light housing to prevent moisture intrusion. After that, your Porsche fog light should be ready to roll for tens of thousands of miles.
