Tools You'll Likely Need:
* Socket set (various sizes)
* Ratchet and extensions
* Screwdrivers (Phillips and flathead)
* Pliers
* Possibly a wrench for the nut holding the wiper arm
* Wire strippers/crimpers (if replacing wiring)
* Shop rags or towels
* Possibly a torque wrench for reassembly
General Steps (Consult your repair manual for specifics!):
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Remove Wiper Arms: You'll usually need to use a wiper arm puller tool (available at most auto parts stores) to remove the wiper arms from the wiper motor spindle. If you don't have a puller, you might be able to carefully pry them off, but risk damaging the spindle. Note the position of the wiper arms before removing them for easier reassembly.
3. Access the Wiper Motor: This is the most variable step depending on your Cheyenne's year and model. You may need to:
* Remove the cowl: This plastic cover sits under the windshield and often needs to be removed to access the wiper motor. This usually involves removing several screws or clips.
* Remove parts of the dashboard: In some cases, parts of the dashboard or interior trim may need to be removed to get to the motor.
* Remove other components: Depending on the design, you might need to remove other components like the linkage or air intake components to reach the motor.
4. Disconnect Electrical Connectors: Carefully disconnect the electrical connectors from the wiper motor. Take pictures or make notes to remember how they connect.
5. Remove Mounting Bolts/Nuts: The wiper motor is typically secured to the firewall or body with several bolts or nuts. Carefully remove these fasteners.
6. Remove the Wiper Motor: Once all fasteners are removed, carefully remove the wiper motor from its mounting location.
7. Installation (Reverse Order): Installation is the reverse of the removal process. Ensure all connectors are securely fastened and all bolts/nuts are tightened to the manufacturer's specifications (consult your repair manual). Reconnect the battery.
Important Considerations:
* Repair Manual: A repair manual specific to your Chevrolet Cheyenne's year and model is highly recommended. It will provide detailed instructions, diagrams, and torque specifications.
* Safety: Always disconnect the battery before working on any electrical components.
* Wiring: Be careful not to damage the wiring harness. If any wires are damaged, they will need to be repaired or replaced.
* Torque Specifications: Tighten all bolts and nuts to the correct torque specifications to avoid damage.
This is a general overview. Without knowing the specific year and model of your Chevrolet Cheyenne, I cannot provide more precise instructions. Consult a repair manual or a qualified mechanic if you are not comfortable performing this repair yourself. Attempting this repair without the proper knowledge and tools could lead to damage to your vehicle.
