Help with no headlights. 1974 scamp. Blinkers come on instead...

I took the philips screws out, and it had almost zero wiggle room. I see i can get the switch plug off, but dont see how i could change it with an inch of clearance. What am i missing?
Thanks for the enlightenment. New at this
Remove negative battery cable. There is one screw holding the fusebox in the way. You may not need to move that ( I do ). Pull headlight switch to full on. There's a small button on bottom or right side of the headlight switch. Push button to release knob/stem and pull it the rest of the way out. Remove switch bezel nut. Switch should maneuver out from under dash with harness connector on it.
