Tools You'll Likely Need:
* Flathead screwdriver (or a wiper arm puller): This is crucial for prying the wiper arm away from the wiper motor splines. A wiper arm puller is safer and less likely to damage the arm or the splines.
* Socket wrench and socket: To remove the nut securing the wiper arm to the wiper motor shaft (usually a 10mm or 13mm, but this varies by year).
* Penetrating lubricant (like PB Blaster): Apply this to the nut to help loosen it if it's stuck.
* Shop towels or rags: To clean up any fluid.
Procedure:
1. Disconnect the battery: This is a crucial safety step to prevent accidental electrical shorts.
2. Raise the wiper arms: Lift the wiper arms to their highest position. This gives you more access and prevents them from getting in the way.
3. Locate the nut: Underneath the wiper arm, you'll find a nut securing it to the wiper motor shaft.
4. Apply penetrating lubricant: Spray some penetrating lubricant on the nut and let it sit for a few minutes to help break any rust or corrosion.
5. Loosen the nut: Carefully use the socket wrench and socket to loosen the nut. Do not remove it completely yet.
6. Pry the wiper arm: This is where the flathead screwdriver or wiper arm puller comes in handy. Place the tool between the wiper arm and the wiper motor shaft (carefully!). While gently applying downward pressure on the arm with your other hand, gently pry the arm counterclockwise. It will likely take some effort and may require some back-and-forth motion. A wiper arm puller makes this much easier and safer. Avoid hitting the windshield with the screwdriver.
7. Remove the nut: Once the wiper arm is free, completely remove the nut.
8. Remove the wiper arm: Carefully lift the wiper arm off the shaft.
Reinstallation:
To reinstall, reverse these steps. Make sure the wiper arm is properly seated on the shaft before tightening the nut. Tighten it to the manufacturer's specified torque (found in your repair manual).
Important Considerations:
* Year-Specific Differences: The exact process might vary slightly depending on the model year of your Chrysler Town & Country. Always refer to your owner's manual or a repair manual specific to your vehicle.
* Wiper Arm Puller: Highly recommended. It prevents damage to the wiper arm and the wiper motor shaft.
* Patience: This process can be tricky, especially if the nuts are rusty or seized. Don't force anything; take your time and use the right tools.
If you're uncomfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic. They have the right tools and expertise to do it safely and efficiently.
