I've got some super slow motion windshield wipers. High speed feels like barely normal speed should. Intermittent is funny to watch.. it gives a little nudge a few times before it the wiper actually makes a pass.

 

I know it's a minor detail... but I am wondering if it is worth pulling out the wiper motor assembly and tearing it down (is this even possible)? In past experience with small parts like this, often a thorough cleaning and re-greasing works wonders.

 

Just thought I'd ask if anyone had any tips... "give it a shot" or "don't waste your time" or "yeah that is exactly what you need to do", etc. Thanks!!!!

It's probably not the motor - it's likely the linkage ball joints, etc under the cowling. The grease dries up and they get stiff.
