how do I take the wiper switch out of the dash on my 67'? i removed the left side heater vent so i can reach up behind it, but i just can find the way it unscrews. Does the front trim peice (forget what they call it) unscrew?
thanks guys, this ones really stumping me, i'm not big on working on stuff, but i need my wipers to work, and I think the connection is just all corroded.

There is a setscrew that takes a small allen wrench to remove the wiper knob 1st.
Once the knob is out of the way You will see a nut that holds the switch in.
Also there is a starwasher between the switch and the backside of the dash....this ensures a good ground of the switch...make sure it does not fall off and get lost in dashland......
