What car are you working on ?
Check the load capacity of the switch always. One will work. Don't need double pole. Are they 2 speed ? A dedicated ground is required.
I'm working on a '32 Ford Tudor and yes I realize that the arms will never synchronize. The switch(SPST) that I'm using is rated for 15 Amps. They're single speed and they both share the same ground. My only concern is to get the wipers moving so that I can safety the car to the satisfaction of the inspector. After that Rain-x will be my wiper mode.
