If you have intermiitent wipers, there is a "control module" between the switch and the motor.
Since your washer works, might try checking the ground coming off the module, the washer motor is grounded seperately on its own.
To eliminate/confirm any o fthe components, you should be able to jump out on the switch side and/or jump the motor directly.
If my Chilton's is correct (and I am reading it right) dark blue to the motor is the hot wire from the ignition, red/yellow, dark green and brown/white are direct from swicth to motor, bypassing the control module.
