I have some trouble getting my brake lights and turn signals to work properly. Right side brake works, and right side turn if I wiggle the lever a bit. Left side brake don't work at all (bulb is ok) and I can get the left turn signal indicator to light up but not flashing. I'm thinking that I need to remove the horn ring and steering wheel to get to the turn signal switch and clean it since I can get some function out of it when I wiggle it and I also have a serious voltage drop from the turn signal lever to the junction block under the dash. I have 6 volts in and out of the flasher relay, but only about 4 volts out of the turn signal lever. I understand that I need to push down on the horn ring and turn it counter clockwise, but do I need to remove the small screws on the backside of the steering wheel before turning the horn ring?
