There is a small green box box behind the drivers side front strut tower. That box is an amplifier for the wiper motor. Give that thing a tap and see if they start working again. If that doesnt do the trick then get yourself a voltmeter and see if the motor is getting B+. If so, next you would check for a voltage drop on the ground wire. Put one lead to the ground wire (through the backside of the wiper motor connector) with the connector plugged in. Put your other lead on the negative battery terminal. With the ignition on and the wipers on highspeed record your voltage reading. If you see any more than a couple mV then you have a ground issue. Easy fix for that though, just hardwire it straight to ground. Good luck friend!
