MAC Posted June 30, 2006 Report Share Posted June 30, 2006 Isn't there a relay? I'm looking at my '94 GM Service Manual and I don't see anything about a relay. It says there is a fuse in the trunk compartment. Everything regarding non-working wipers indicates either a blown fuse, defective switch assembly, motor, bad ground connection, or open in power feed circuit.

JimD Posted June 30, 2006 Report Share Posted June 30, 2006 Not a whole lot to the circuit. Power from the ACC (10 Amp) fuse in the underhood fuse box. If the switch is giving you 12 volts on pin H of the wiper connector, you might try a redundant ground jumper from the motor frame to some convenient chassis location. Jim Drive your car.
