How can I tell if my car switches are dying?

Different switches can start to fail in different ways. Something like a window switch, for example, won’t be as crisp as it used to be and start to feel rough and have glitches whenever you use it, but continue to function fine. Sometimes you’ll have to use extra pressure on the switch to get whatever it’s controlling to work. A multi-function switch, like a headlight switch, may exhibit the same symptoms, or one of the systems it controls may not work. Another issue is if the parking light position on the headlight switch works, but nothing happens when you turn it to the headlights-on position. This is something you don’t want if you have to drive on a dark and stormy night. Of course, it’s best to address any switch issue as soon as possible, before you’re left with total failure at the most inconvenient time.
