65 Chevy C10, trying to figure out why wipers won't work. I have power to the dash switch

I have power to the yellow and blue wires at the motor.

and I have power to the wiper fuse. Does it seem more likely the switch or the motor bad?
Thanks

test for both being bad, bypass the switch and wire the motor hot. or take a volt meter out and test for complete circuit with the switch on. if you switch the voltmeter to the beep, and test with the switch on, it should beep if you have one wire connected to each side of the switch.

this will eliminate your problem. additionally, trace down your ground and ensure its secured in a good spot and not rusted or corroded

I do notice that the back of the switch has two tabs but only a blue wire attached. Not sure now if it's single speed switch/motor or now???

Wiring diagram says only one blue wire goes from motor to switch. Ran a wire from the blue wire on back of switch to ground and wipers started working. One speed motor. Motor runs all the time with ignition on. May mean bad switch??

yes replace the switch its shot, unless of course a wire has been broken from the switch to the motor.
