I'm down today so I decided to try to figure out the turn signals. I took out the instrument panel. Two questions then some whinging and another question. 1. What is the switch on the back of the instrument panel for? see pic. 2. This relay is what is buzzing (The flashers are now working IDK why) What is it and how do I test it. OK that's two in one.

I tried to get the column cover off. It has never sat right since I took it off when I first bought it. I cannot see up the inside hole mainly because I cannot get under to see it and my screwdriver will not take purchase on anything. How does one get at it? I'm tempted to take the bench out.
