Wiper Motor Repair

My wipers worked erratically, then stopped completely.  For a while, I was able to get them to work by slamming the hood, or rapping on the hood latch.  I assumed the motor was bad, and started to research the Honda wiper motor conversion.  I decided to remove the old motor and take a look before I ordered anything.  After studying the cryptic wiring diagrams, I decided to try and bypass the relay mounted on the wiper motor and go straight to the windings.  When I did this, the motor ran very reliably in both the low and high speeds.  I took the cover off the relay, cleaned all the contacts, and it worked fine!  I reinstalled the motor on the car, and it works better than ever.  So, cleaning this relay may solve a similar problem, and avoid a motor conversion.
