Fuse Blows?

ON my 81 VW Vanagon, the fuse(16amps) going to the windshield wiper motor keeps blowing. I looked at the wiring diagram, just before the fuse is a LOAD REDUCTION RELAY. With engine running, I checked voltage at the fuse box(at the fuse that keeps blowing) 13.9 volts. Should the LOAD REDUCTION RELAY lower the voltage before it gets to the fuse or could it be something on the other side of the fuse blowing it?:banghead: ....:frown:

It would have to be something on the ground side of the fuse causing the circuit to overload. Something shorted or maybe even the motor is drawing too much. Check to see that the wiper shafts are not seizing up or binding - causing the motor to work too hard.
