What are the Symptoms of Rear Wiper Motor going bad or quirky

Couple observations

Notice once when it came to rest,it was resting on the opposite side.
Triggering the wipers, it would wipe and then come back to rest on the wrong side

3-5 Times, when it hits *tension-resistence*, even of very light load, it will stall out. Stall to the point, where even engaging it off/on, the wiper won't even move past the point where it stalled. Turn off ignition, and turn it back on, wiper off/on will resume it's proper movement.

For example, on above, we had some light dusting of snow. With the sun, maybe mildly wet. But not heavy enough to impede movement. Front wiper wiped the snow off just fine. Rear wiper went halfway and stalled out. No matter how many times the rear wiper was triggered off/on, it would not move at all. Ignition reset and all is well.

I recall this issue happening now and then over the last 3 years
