73 (early) fj40 windshield wiper problem: I have read ALL on the subject via this site. Proud to say that after LOTS of hours my wiper system works! HOWEVER, even while spraying water on windshield the old motor just don't want to go good. Yes, it has low & high speeds (full switch pull out is a little faster that first position). I cleaned out old grease and changed out the 3 half worn brushes -- could the problem be wrong grease and.or junk brushes? I got some cheap China made brushes and carefully sanded them to proper size - shunt wires go out sides as they should. Maybe I should take the wiper blades off and let her run for an hour to lossen it up or seat the brushes or ..... hell, I don' know. HELP I could roll the window down and reach outside during storms to assist my wimpy wipers.
