As the motor pumps the water for both the front and back washers that must be a valve that controls whether the water goes to the front or the back washers. This is probably faulty (stuck in one position maybe ?) and will more than likely need replacing.
Cant see it being your motor at fault.
Co-incidentaly I have the exact reverse problem on mine, I get a dribble out of the back windscreen washer, but the fronts are fine!
Let us know how you get on.
