    how to replace turn signal switch

    I have a 97 chevy s10 4x4, the hazard light and headlights are fudged up. I can see that the turn signal lever on the left of the steering column has a problem with the turn signal lever/switch. I'm not sure if I am using the right name for it, so hopefully you know what I'm talking about. I can tell you that the hazard lights on/off switch broke a while back and I squeezed a screw down the side of it to keep the Hazard lights off. I have sense noticed the the screw was wedged against a copper conductive tracer and I think this effected the head lights some how and made the turn signal unit defective. I took the steering console cover off and dash board cover off and I can see the turn signal switch which I also removed but I don't see how the wires disconnect. I have re connected the switch so I can drive the truck.

    So what is the trick here?
