C4 1994 wipers not working
 

I Have power from fuse to the circuit board that covers the wiper motor. I had removed the 3 torque screws that held on the cover to the motor and checked the 2 terminals for voltage that come in from the side. It seems the power comes in the right side harness and exits the TOP harness with 3 terminals. The left terminal on the TOP connecter feeds the washer motor, the center is ground and the other terminal I assumed feeds the wiper motor? I grounded the center terminal and applied voltage directly from the battery to the terminal I believe feed the wiper motor but got nothing.
While looking online for a motor I read that there might be a wiper motor relay and or switch somewhere???:confused: DN966 wiper switch, http://www.ebay.com/itm/Standard-Mot...sories&vxp=mtr

1. Is there a wiper switch and if there is, where would it be?
2. Is there another way I can directly identify the propblem?
3. What kind of wiper motor should I get? AC Delco or Cardone?

I would hate to buy a wiper motor and or circuit board and then find out it was a switch. Circuit board also seems to be OK except one of the relays in the board did not switch when I applied voltage.

thanks in advance for any input.
