Wiper Motor brushes

Ballest resistor is for your low speed...without it you only have high. Brushes are an unusual shape so they are kind off hard to find. Card one is the usual half azz rebuilder....they like others are not really rebuilders...they are more like fixers....find problem...fix it....everything else is fine. I would just use the brushes out of the car done in your motor but be careful...the brush landings break fairly easy.
