Been working on my wiper problem more: Cleaned and bench tested wiper motor, and it works ok. Wiper switch seems ok, and so does the relay (tried a second relay as well).

When testing the wiper motor plug, the polarity reverses between the power and ground leads at high speed, causing the wiper motor to go counter clockwise on low, and clockwise on high.

#1-Is this normal?

I need an electrical diagram of the wiper system or the whole car's electrical system to find where it is supposed to be grounding.

#2-If anyone has these diagrams, or knows where I could find them, could you point it out for me?


Thanks,
Mark

invest in a haynes or similar repair manual. it'll most definitely come in handy, both now and next time you have trouble of some kind.

Yeah I have Haynes but it doesn't get into detail on that circuit, so I went out and picked up the Bentley this weekend. $60.00 Canadian but worth every penny!
I'm sure I'll get to the bottom of my problem very soon now.
