There is a clip on the base of the wiper arm that swings out. Then you just lift the wiper arm up and off. Very simple once you know what to do. ( no, I'm not that smart. A guy at NAPA showed me how to do it.) Hope this helps. B.

Same problem here. Check for a short in the wiring under the dash before replacing anything. I replaced the integral switch and the motor/module assembly and yet......they keep going and going and going. After shelling out 250.00 I wished I would of investigated a little more. My problem is the black wire from the ignition switch to the splice pack/ ground terminal is burnt. and also charred about 6 other wires. 3 of which pertain to the wiper switch assembly. I don't know if this helps, but hopefully it will.

Body control module (BCM)
Wiper 1 relay
Wiper 2 relay
Windshield wiper motor
Windshield washer pump
Windshield washer nozzles
Windshield washer solvent container
Windshield wiper arm and blade assemblies
Windshield wiper transmission
WIPER/SW 10A fuse
WIPER 25A fuse
The body control module (BCM) controls the wiper motor based on input from the windshield wiper washer switch. The BCM monitors the wiper washer switch through three separate signal circuits and a ground circuit. The windshield wiper switch high signal circuit is used to determine high speed wiper operation, the windshield wiper switch low signal is used to determine low speed, intermittent, and mist operation through the use of a resistor ladder, and windshield washer switch signal circuit is used to determine washer operation. The windshield wiper motor park operation is controlled by the BCM. The BCM recieves an input from the park switch to determine wiper blade position. When the wiper blades are at the bottom of the windshield glass in park position the wiper park switch will open and the circuit will be pulled up to B+ by the BCM. The park signal will be pulled to ground by the wiper motor park switch while the wiper blades are not in the park position.
The BCM controls the windshield wiper motor through two output controls, controlling two relays which determine the desired wiper speed, high or low
Diagnostic Trouble Codes (DTCs)
The body control module (BCM) monitors the voltage on the windshield wiper switch signal 2 circuit for diagnostic purposes. If the circuit is shorted to voltage while the driver is commanded OFF, the BCM will store DTC B3715. If the circuit is shorted to ground while the driver is commanded ON, the BCM will store DTC B3715. Refer to DTC B3715.
It would be best to have a factory scan tool to diagnose this problem . it would make it easier anyway .
