Not trying to be funny... Some motors aren't strong enough to sweep dry glass.... Even some electric ones. If they can't finish the sweep, the arm won't go 'around the horn' to do the return. Have you tried removing the arms and checking the motion of the mounts?

Had to clean and lubricate that and helped a bunch. | | | | | Joined: Oct 2009 Posts: 136 Wrench Fetcher | | Wrench Fetcher Joined: Oct 2009 Posts: 136 | My vacuum motor would only go one way, I opened the valve chamber and cleaned the dirt out of it and oiled it very thoroughly. Re-assembled and it works great. The valve chamber is under the cowl vent so vacuum tends to suck in dust and dirt. | | | | | Joined: Jan 2005 Posts: 1,602 Shop Shark | | Shop Shark Joined: Jan 2005 Posts: 1,602 | Mine had the same problem. Clean and oiled, it works like new.

Seemed like it was a bump that was in the mold but i don;t see how it would have worked. So i sharpened a screw drivier and wittled down the aluminum till it was flat and then sanded it with fine sand paper, regreased and it worked good after that. | | | | | Joined: Mar 2002 Posts: 9,115 'Bolter | | 'Bolter Joined: Mar 2002 Posts: 9,115 | If I remember correctly they have a reversing valve that causes it to go back. If something is causing it to hang up then it might produce your symptoms. I would clean it up, oil it and try it before installing it again. | | | | | Joined: Jan 2000 Posts: 2,074 'Bolter | | 'Bolter Joined: Jan 2000 Posts: 2,074 | You still should check your vacuum, gauge is cheap and also a great tool for tuning up the motor. You should have close to 20" of vac. | | |
