After all this talk of wiper motors I decided to disassemble mine to check it for condition. My motor has always been very weak and will hardly move the wiper on a dry glass. I realize this is somewhat typical of our cars. Upon disassembly I was surprised to see the inside completely clean an looking like new. Maybe too new in fact. The brushes are so new they are not bedded AT ALL and make hardly any contact with the commutator as they are flat and the comutator round. I am sure I could get better torque on the motor if the brushes were properly bedded. Does anyone have any ideas on how I could do this? I have thought about taping some sandpaper to the comutator and spinning it in the housing to wear the brushes to a more acceptable contact patch but the brushes look to be pretty cheaply mounted with little lateral stability so I do not know if this will achieve the result I am looking for.
