Windshield Wiper/Washer System Components
The windshield wiper/washer system consists of the following components:
• Windshield wiper/washer switch
• Windshield wiper motor
• Windshield washer pump
• Windshield washer relay
• Outside moisture sensor
• FRT WIPER 25A fuse
• W/S WASH 15A fuse
Windshield Wiper/Washer System Operation
Accessory voltage and ground is supplied to the windshield wiper motor and provides the power for operating the wiper motor and logic power to the wiper motor module. The WASH, MIST, LOW, and DELAY modes are controlled by the windshield wiper/washer switch through a series of internal resistors. The windshield wiper switch supply voltage circuit is a 12-volt reference from the wiper motor module to the wiper/washer switch, and the switch position determines the point on the resistor assembly where the reference voltage is applied. The windshield wiper switch signal 1 circuit supplies the voltage from the resistor assembly to the wiper motor module and the signal voltage determines the operating mode. High speed operation is controlled by the windshield wiper/washer switch through the windshield wiper switch high signal circuit. The windshield wiper switch high signal circuit is supplied 12 volts by the wiper motor module and when the wiper/washer switch is turned to the HIGH position the windshield wiper switch high signal circuit is grounded through the switch ground circuit. The windshield washer pump is controlled through the windshield wash relay. The windshield wash relay coil and switch is supplied battery positive voltage, and during WASH mode the wiper motor module grounds the washer relay control circuit energizing the relay. When the relay is energized battery positive voltage to the switch side of the relay is supplied to the washer pump control circuit.

The is the symptom of a defective wiper switch.

Hello, Here is a picture of the wiring diagram, Hope this helps!

Best Wishes and Good Luck!

Looking at the Diagram the power for the washer pump goes from the multi-function switch on column to the pump for domestic vehicles and the power fuse also runs the wipers so if it was the fuse your wipers would not work. The fuse in the PDM in the engine compartment is for a another option so it may or pay not have a fuse. so since the motor works by jumping power to the wire in the engine compartment. Than that leaves a bad switch or a broken connection in the wire between the switch and the bulkhead connector through the firewall.

The wiper arms have a push in tab at the very bottom at the fitting that is pressed into the wiper linkage below the screen. Use a flat headed screwdriver to pry out the tab. Once out the arm can be pulled right off. Now you can remove the cowling screen

I have most all of the wiring diagrams for your vehicle. Can you narrow down what you need as there are many? If you need me to send them to you then send me your email address.
