1. Preparation:
* Disconnect the battery: This is a crucial safety step to prevent accidental short circuits. Disconnect the negative (-) terminal first.
* Locate the wiper arm nut: Under the wiper arm, you'll find a nut (often a large one). It's usually hidden under a plastic cap; pry this cap off gently if needed.
2. Loosen the Nut:
* Use the correct tool: You'll need a socket wrench or wrench that fits the nut. The size will vary depending on your Venture's year. Consult your owner's manual or a repair manual for the correct size.
* Loosen, don't remove entirely: Loosen the nut just enough to allow the wiper arm to move freely. Don't completely remove the nut yet.
3. Release the Wiper Arm:
* Position the wiper blade: This is the trickiest part. You need to position the wiper blade so it's roughly perpendicular to the windshield, making a 90 degree angle. This is essential to prevent damage and help the arm lift off.
* Lift and wiggle: Gently lift upward on the wiper arm while still loosening the nut slightly. You may need to wiggle it back and forth to break the connection between the arm and the splined stud. Apply gentle but firm upward pressure. Force is usually not needed if the nut is loosened enough and the blade is perpendicular.
4. Final Removal:
* Once free: Once the arm is free from the stud, completely remove the nut.
* Inspect the stud: Look at the stud; make sure it's not damaged. Clean the stud and area around it before installing a new wiper arm.
Important Considerations:
* Stubborn arms: If the arm is extremely resistant to removal, try using a wiper arm puller tool. These are available at most auto parts stores. Never use excessive force, as this can easily break the wiper arm or damage the stud.
* Rust and corrosion: If your Venture is older, rust and corrosion can make this process more difficult. Penetrating oil (like PB Blaster) applied to the nut and the connection point can help loosen things up. Let it sit for at least 30 minutes before attempting removal.
* Year and Model: The exact procedure might vary slightly depending on the year and model of your Chevy Venture. Consult a repair manual specific to your vehicle for detailed instructions and diagrams.
Remember safety first! If you're not comfortable performing this task yourself, it's always best to take your vehicle to a qualified mechanic.
