I've been pricing out a new signal switch, and have yet to find one under $150. I took it apart this morning just to find it's attached to the wiper switch too (why would they do that?), and that's why it's so pricey.
The reason I'm replacing it is because there's a short somewhere that makes the factory fog lights flash when you hit a bump or wiggle the switch, even when the headlights are off. I ended up taking the fog lights off until I can get a new switch.
Has this happened to anyone else before?
