Was riding around Silver Lake Dunes and my shift indicator went out on my 1995 k1500. I have 4 on the floor but will not engage or light up unless indicator works. Also wipers will not work. When the indicator light goes off it seems the ABS is in sync. If I mash on the throttle or hit any real big bumps it will flicker on and will have full functions again. Recently put a 6 inch on and re-geared to 4.56. It had previously flickered alittle here and there right after the gears were installed but I'm just not sure where to go next. I'm not sure if I have to rip the pan off and check the wires in my 4l60e or what. Maybe it could be a ignition switch but I move the key in and out and play with it and have no signs of that either. Seem to have a real head scratcher on this one. Any leads would be awesome.
