68 Stang - Remove Dash, Test Blower Motor
 

I need to remove my 68's dash to do some work. How do I remove it?

I also need to see if my heater blower motor is good. I've already removed the entire assembly. It's a 3-speed switch, and there are two wires coming from the motor (brown and yellow). How can I test this motor to see if it's good?
