How do I bench test a windshield air motor

[harleyman_1000]

I would recommend carrying RainX or something similar, no wipers required...

  Yes I used rainX from Phoenix to St. Louis, but need wipers to pass the safety inspection for plates here in Missouri

Move to north carolina.  anything this old does not have to be inspected.

PS i guess that they know that anything this old and still running has been taken
care of.  Most of my vehicles are like that, as old as me.

The buses and trucks with electric wipers the motor is 3 times as big as the add on system I bought a set for the Eagle and never installed the system they just looked cheap made to me for 800 bucks,Summit Racing has a lot better looking system for less than 400 that can be made to work fairly easy to each his own 

quick check shows the Autoloc kits cheaper direct from manufacturer today.
