Here's a general guide. Specific steps and locations may vary slightly depending on your exact Venture model. Always consult a repair manual specific to your vehicle year and model for precise instructions and diagrams. A Haynes or Chilton manual is a good investment.
Tools you'll likely need:
* Socket wrench set (metric)
* Phillips head screwdriver
* Flathead screwdriver (possibly)
* Pliers (possibly)
* Rags or shop towels
* Possibly a torque wrench (for proper reassembly)
Steps (General):
1. Locate the Motor: The rear wiper motor is usually located under the rear cargo area. You might need to remove some trim panels or access panels to reach it. Look for the motor arm connected to the wiper arm on the rear window. The motor itself is typically attached to the body of the vehicle.
2. Disconnect the Electrical Connector: Carefully disconnect the electrical connector from the rear wiper motor. Sometimes there's a small tab you need to depress to release the connector.
3. Disconnect the Wiper Arm: You'll need to disconnect the wiper arm from the motor shaft. This might involve using a wrench or pliers to loosen a nut or bolt. Mark the position of the wiper arm relative to the motor shaft before disconnecting to ensure proper reassembly.
4. Remove Mounting Bolts/Nuts: Identify and remove the bolts or nuts that secure the rear wiper motor to the vehicle body. The number and location of these fasteners will vary.
5. Remove the Motor: Carefully remove the motor from its mounting location. It may be slightly tight, so take your time and use appropriate force.
6. Inspect the Motor and Surroundings: Once removed, inspect the motor for any obvious damage or wear. Also, check the area where the motor was mounted for any rust or corrosion.
Reassembly:
Follow these steps in reverse order, ensuring the wiper arm is correctly aligned with the motor shaft as noted earlier. Use a torque wrench if you have one to tighten the mounting bolts to the manufacturer's specification (found in a repair manual).
Important Considerations:
* Access: Accessing the motor can be tricky depending on your Venture's configuration. You may need to remove interior trim panels to gain access. Be gentle to avoid damaging the panels.
* Rust and Corrosion: Expect some rust or corrosion, especially in older vehicles. Use penetrating oil if necessary to loosen any stubborn fasteners.
* Repair Manual: A repair manual is highly recommended. It will provide detailed diagrams and instructions specific to your 2001 Chevy Venture, avoiding potential damage.
This is a general guide. Consult a repair manual for your specific vehicle before attempting this repair. If you are not comfortable performing this repair yourself, it's best to take your vehicle to a qualified mechanic.
