A long time ago out of curiosity I bench tested my spare unrestored "077" wiper motor. Here's what was measured with my meter:

Slow speed = 3.0 amps
High speed = 4.3 amps

Of course, once you add all the linkage, arms and friction between blades and windshield the draw will be much higher respectively.

Excellent information, thanks.
