On the dash of my 91 crx si to the right of my sunroof switch theres a small black switch that no one seems to know what it's for or what it does. I. Turn it on and nothing seems to happen. Anyone know what its suppose to be for....the car doesnt have an alarm or fog lights.

 

Bumpity? Anyone?

 

Take a picture but it sounds like it's an aftermarket switch that someone put in. The only way to check it would be to simply pop it out and track the wires down. It shouldn't be that complicated.
