Frigiking AC and Windshield Wipers.

[gstorek]

Trying to fix two items on our '71 280SL. 
For the Frigiking AC, we need a new on/off switch.  Any suggestions on where to find one?
Also, windshield wipers are not working, not that we would ever drive it in the rain, but would like to have them in good working order.  The switch seems ok, so it looks like we need a new motor.  Again, any suggestions of where to source this will be greatly appreciated.
Thanks!

I always remind people to work (or buy parts) based on facts.  Use a multimeter to ensure the where the wiper system does or doesn't have power.  If it hasn't moved in decades, the apparatus under the dash could be seized.
