You have all heard this before - It worked when I parked the car a few years ago. Well, it's true, the wipers worked fine before the engine was replaced. All of the wiring is intact and there is power to the motor. The pump runs when the switch is pressed but no movement from the wipers. Any ideas?
 
IF you messed with engine, there is a black wire that used to go to either a starter mounting bolt, OR bellhousing bolt, and I bet you have it on the battery post terminal on the starter.....common mistake, black wire ground for both the HVAC blower motor and the wiper motor....

when I rewired my car, one of the first things was heavy up that wire for the C4 blower motor, and bring it up top to the intake manifold bolts......along with all the injection grounds.....:drink:
