Without knowing what kind of vehicle it is, you could create a simple relay circuit to relay intermittent power send to your front wiper motors to the power wires to the rear wiper motor:

SPDT Relay (30A, 12 volt):

85: chassis ground

86: 12 volt positive motor wire from either of the front two wipers

30: 20A fused 12 volts (from battery)

87: output to rear wiper switch (at stalk or on dashboard) (if it's on the stalk, you can find the wires in the wire loom under the steering column)

hope this helps
