Actually, a wiper assembly that refuses to move might have a simple blown fuse. But usually fuses don't blow on their own. Even at full stall, the current draw of the motor should be well below the fuse's rating. If the fuse is blown, odds are there's something else wrong, like a shorted wiper-motor armature or faulty wiring anywhere along the harness between the motor and the switch. Even a mechanical problem like a seized bushing can make a fuse eventually fail.
The fuse is okay, or you've replaced it with one that has the appropriate amp rating. There's still no action? With the wipers and ignition on, whack the motor assembly with the handle of a screwdriver or a rubber mallet. If that gets things moving, you've got a bad commutator or an open winding on the armature. When the motor parks, if the brushes are sitting on the bad segment, no current flows. Whacking the whole business smartly can sometimes jolt things into motion. Because there are often a dozen windings on the armature, the motor runs fine until the next time it comes to rest on the bad spot.

Jiangsu Jiesheng 20KN hand winch supporting 110m oil barge
On October 15, the world's second-generation 110-meter oil barge built by Taizhou Sanfu Shipbuilding Co., Ltd. was successfully delivered. The whole ship mooring system used the 20KN hand-cranked winch manufactured by Jiangsu Jiesheng Anchor Machine Company. The time for Jiangsu Jiesheng to deliver the hand-cranked winch was less than 30 days on October 15th. Our Chenggong and business managers rushed to Taizhou Sanfu Shipbuilding to visit the shipyard engineers and shipowners' supervision team to confirm the technology of hand-cranked winch. Requirements, dimensions and actively cooperate with the shipyard to confirm the position of the winch on the ship, and timely and efficiently provide the shipyard with the required drawings and base drawings of the 20KN hand winch.
