I have 88 IROC
the trouble im having is no signal lights, I have Hazard lights but no signal..
I replaced the signal clicker and still have hazards but no left or right signals.
please help

 

its more than likely the actual selector. take your plastic of the column, and the steering wheel if nessacary. there should be metal contacts for where the switch hits to complete the circuit. i actually had mine wear through on my geo tracker, and fixed it by wadding in some aluminum foil

 

There are two flashers. One on the fuse panel for the turn signals and one on a convienece center for the hazard. Check the turn signal fuse? Check for power going to the flasher. All your bulbs good? All else fails then it may be your signal switch

 

problem fixed it was the second switch that i didnt see in its hiding spot
