Tools you'll likely need:
* Socket set: Various sizes, including metric and possibly SAE.
* Wrench set: Similar to the socket set, including metric and possibly SAE.
* Screwdrivers: Phillips and flathead, various sizes.
* Pliers: Needle-nose and possibly slip-joint.
* Ratchet and extensions: To reach tight spaces.
* Wire strippers/crimpers: If you need to replace wiring connectors.
* New pulse wiper motor: Ensure you get the correct replacement for your van's model.
* Shop rags or towels: To keep things clean.

General Steps:
1. Disconnect the Battery: This is crucial to prevent electrical shorts and injury. Disconnect the negative (-) terminal first.
2. Access the Wiper Motor: This is usually located under the cowl (the area beneath the windshield wipers). You may need to remove parts like the wiper arms, wiper linkage, and possibly the cowl itself. Consult your repair manual for specifics on this. Removing the wiper arms typically involves using a wiper arm puller tool to avoid damaging the arms or the windshield.
3. Disconnect Electrical Connectors: Carefully disconnect the electrical connectors from the wiper motor. Take pictures or make notes of the connections to ensure correct reassembly.
4. Remove the Wiper Motor Mounting Bolts: The motor is usually held in place by several bolts. Carefully loosen and remove these bolts.
5. Remove the Wiper Motor: Once the bolts are removed, gently remove the wiper motor from its mounting location. It might be a bit tight, so use gentle force and leverage as needed.
6. Install the New Wiper Motor: This is the reverse of removal. Ensure the new motor is correctly aligned before tightening the mounting bolts.
7. Reconnect Electrical Connectors: Carefully reconnect the electrical connectors to the new wiper motor, matching them to your notes or pictures.
8. Reassemble Everything: Reinstall the cowl, wiper linkage, and wiper arms in the reverse order of removal.
9. Reconnect the Battery: Reconnect the positive (+) terminal of the battery.
10. Test the Wipers: Turn on your wipers and test their functionality. Ensure they operate correctly in all speeds and that there are no unusual noises.
Important Considerations:
* Repair Manual: A repair manual specific to your 1995 Chevrolet van is highly recommended. It will provide detailed instructions, diagrams, and torque specifications.
* Safety: Always disconnect the battery before working on electrical components.
* Wiring: If the wiring to the motor is damaged, you may need to repair or replace it. This may involve soldering, crimping, and using heat shrink tubing.
* Parts: Ensure you purchase the correct replacement wiper motor for your specific van model.
This is a simplified overview. Attempting this repair without experience or proper tools can lead to damage or injury. If you're not comfortable performing this repair yourself, it's best to take your van to a qualified mechanic.
