I checked the archives...a bunch on wiper motors. Still, I could use some help. Motor and switch are grounded. When switched on the motor or something clicks and thats it. I have taken motor off of car and checked behind plastic cover and "things" look okay, plastic gear will turn manually and move internal "arm". What next, should I go deeper by removing plate and "stuff" on top and if I do what should I be looking for? I did also take two long screws out holding motor and pulled motor back to visaully check for broken wires, or other unusual looking things. Did not see anything suspicious. Any ideas? Thanks..
