3. Contour up the mount holes on the brand-new washer Engine with the mount bolts on the firewall. Use your digital volt ohm meter to test the positive lead to the input in the module. Check the ground circuit using the ohms setting on your digital volt ohm meter. Low or no voltage at the module may indicate failure of the module or bad wiring. These are simple steps so if you have to force anything you are doing something wrong. Check your procedure and try again.
4. Locate the new motor's grounding strap. Install the free end over the mount bolt and secure the nut with the open end box wrench or ratchet set. Tighten mounting nuts in a star pattern so that the washer motor is flush against the firewall.

If not, you have a faulty part that needs to be taken back to the vendor and exchanged for a new one. Make sure you reconnect the wire plug to the relay. The motor will not operate from the drivers console if it is not plugged in.
6. Wiper motors have a feature that allows the wipers to keep moving after the switch has been tuned off. This module holds enough residual electricity to function the wipers until they are in the "Park" position at the base of the windshield, so they do not obstruct the driver's view. Test the continuity of the wires running in and out of the control module. Do a visual inspection for burned or melted wires and insulation. The wiring must be repaired using your splicing/wire connector before the module can be checked accurately. Push the Engine onto the mount bolts and secure it in country with the mounting nuts using the extensive boundary box edge wrench or ratchet establish.
