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.

Luding copper mine joint development
Yunnan copper-containing sand basin sedimentary deposits, deposits occur in the interaction of light and sandstone purple band stratoid output, long in the longitudinal direction (inclined) long 719 279cm, minor axis direction ~ 70 ~ 800m, The average is 370m, the thickness is 3.91~5.0m, the inclination angle is 2°~29°, and the vertical depth is about 575m. The ore is stable. According to the natural type of ore and the ore elevation of the ore body, it is divided into three sections: upper, middle and lower sections. The design of the central mining section is planned in advance, and the designed production capacity is 1500t/d, which actually reaches 800~1000t/d.
The deposit is jointly developed by the inclined well of the bucket and the inclined well of the blind bucket (the later section of the lower section of the mine is re-connected with a blind-chain inclined shaft). The development system is shown in Figure 1.
