1. Diagnosis:
* Check the fuses: Before diving into the motor itself, check the fuses related to the wipers in the under-hood fuse box. Your owner's manual will show you the fuse layout.
* Check the switch: Make sure the wiper switch itself is functioning correctly. Try different settings (intermittent, low, high). A faulty switch is a common culprit.
* Check the wiring: Visually inspect the wiring harness leading to the motor for any obvious damage, fraying, or loose connections. Pay close attention to the connectors at both the switch and the motor. Use a multimeter to check for continuity if needed.
2. Accessing the Motor:
* Park and disconnect the battery: This is crucial for safety. Disconnect the negative terminal first.
* Remove the cowl: This plastic cover sits under the windshield and protects the wipers and their mechanism. You'll likely need a few screws and possibly some clips to remove it. Consult a repair manual for the exact location of these fasteners.
* Locate the wiper motor: Once the cowl is off, the wiper motor will be visible. It's typically located near the base of the windshield on the driver's side.
3. Replacing the Wiper Motor (if necessary):
* Disconnect the wiring harness: Carefully unplug the electrical connector from the motor. Take pictures or make notes of how it's connected if you're unsure.
* Remove the wiper arms: Use a wiper arm puller tool to remove the wiper arms. These tools are inexpensive and prevent damage to the wiper arms.
* Remove the motor mounting: The motor is typically held in place with bolts. Remove these bolts to free the motor. Again, your repair manual will show the exact locations and type of fasteners.
* Install the new motor: Install the new motor in reverse order of removal. Ensure the mounting is secure.
* Reconnect the wiring harness: Carefully reconnect the wiring harness to the new motor.
* Reinstall the wiper arms: Carefully reinstall the wiper arms using the wiper arm puller tool. Ensure they're securely attached.
* Reinstall the cowl: Reinstall the cowl, making sure all screws and clips are properly secured.
* Reconnect the battery: Reconnect the battery's negative terminal.
4. Testing:
* Test the wipers: Turn on the ignition and test the wipers on all settings.
Important Considerations:
* Repair Manual: A repair manual specific to your 2000 Ford F-250 is highly recommended. It will provide detailed diagrams, torque specifications, and step-by-step instructions. Haynes and Chilton are reputable publishers.
* Tools: You'll need basic hand tools such as sockets, wrenches, screwdrivers, and possibly a wiper arm puller.
* Parts: Purchase a replacement wiper motor that's specifically for a 2000 Ford F-250 7.3L. Ensure it's the correct part number. Auto parts stores can assist with this.
If you're not comfortable performing this repair yourself, it's best to take your truck to a qualified mechanic. This process involves working with electrical components and potentially sharp objects. Improper repair could lead to further damage or injury.
