Trico Wiper Motor Moves Only One Direction
I just finished rebuilding the original Trico motor on my 1930 standard roadster. When I pull out the sliding switch the wiper blade moves to the left and stops. When I push in the sliding switch the wiper blade returns to the opposite side and stops. One of you Model A people can diagnose the problem. Looking forward to hearing from you. Thanks.

Re: Trico Wiper Motor Moves Only One Direction
After rebuilding mine complete with new paddle seals (?) it was quite stiff and needed to be encouraged by manual assistance. Only been a couple of weeks so it still needs encouragement. My next "exercise" for it will be using the vacuum from my shop vacuum to help it to break in.
I will tape one end of some vacuum hose into a small vac nozzle I have for cleaning small crevasses and let the uninterrupted vacuum exercise the unit into smooth operation. Sound great in theory. Chap |

Have you tried it with the windshield wet ? When it comes to a wiper it needs water for lube for the blade to flow smoothly. Just a thought

Re: Trico Wiper Motor Moves Only One Direction
I don't think a shop vac has enough vacuum to run a wiper.
Are you sure the wiper switching mechanism is flipping over when the wiper reaches the end of the stroke? Also, as John said, the glass should be wet. |
