If the problem is not in the switch, then there could be a bad relay in the circuit (if so equipped), loose fuse, bad ground, and/or the motor could have a bad (intermittent) connection on the armature. Also, of course, you could have a combination of these electrical faults. It’s easy to diagnose.

What happens if there is no power to the wiper?

If there is power, the motor is bad. If there is no power, although the motor could “still” be bad, you first want to trace the circuit back to the power source to figure out where the break is. Once the circuit is fixed, of course if the motor still doesn’t work, it’s condemned and replaced.
