I have two Trico wiper motors that I am rebuilding, and both once worked a few years ago. (These are not the early motors, which used two screws to fasten the cover of the reversing lever assembly to the body.) I have used 400-grit paper on the air chambers, and I have blown out the air passages.

I have oiled the paddles and used Vaseline in the air chambers. There does not appear to be excessive resistance when I move the paddles back and forth manually. When I apply engine vacuum to the motors, I do not detect any hissing (leaks), but I don't get any movement of the paddles. Is there a way in which one can isolate whether the paddles are at fault? (Bratton's tells me that they no longer have a supplier for the paddle rebuild kits.)
