Why would windshield wipers on 71 beetle stop working - red light on speedometer comes on and blinkers are blinking?

Check the fuse for the wipers and make sure the connections are tight. There are actually TWO red lights on the speedo that could come on. One is the Gen light and the other is the oil pressure light. If the Generater light is on, check to make sure the wires are tight on the Gen. Or It may have gone bad. If the Oil Pressure light is on, make sure the wire is connected to sensor or fuse is good. Don't drive it until your sure your getting oil pressure. Disconnect the wire at the sensor and see if it has power with the key on. If you have power then try replacing the sensor.
