Improper turn signal function?
submitted by Charlie Binder
The problem with the turn signals not working correctly is in the hazard switch, which is located on the dash, just behind the hazard button. The GM solution will most likely set you back close to $400, because their solution is to remove the entire dash to get out the switch. The solution indicated below took me and hour and a half from start to finish and is done with from the cavity when you remove the radio.
The essential overview of how to proceed is:
Pop off the hazard switch button – use a flat screw driver to pry it out
Remove the waterfall
Remove the console/armrest
Remove the radio bezel
Remove the radio
Disconnect the wiring on the rear of the hazard switch
Pop out the hazard switch
Press in the new hazard switch and reverse above steps
Detailed photos of how to get the radio/dash bezel off are found at, but note that these instruction go much further for removal of gauge cluster! http://www.vetteessentials.com/instructions/g_bezels/bezel_howto.html
The next link is the reference to this procedure and some hint from the forum.
