Serial Number: ART001

Introduction

The Jeep YJ, produced from 1987 to 1995, is a versatile vehicle that remains popular among off-road enthusiasts. However, one common complaint among YJ owners is the inefficient stock wiper system. Upgrading the wipers can significantly improve visibility, ensuring safer driving in rain, snow, and other inclement weather conditions. This article provides a step-by-step guide to upgrading the wiper system on a Jeep YJ.

Prerequisites

Before beginning the upgrade, it is crucial to gather the necessary tools and components:

New wiper blades (recommended: Bosch Icon or Michelin Endurance)

New wiper motor (optional: heavy-duty or variable-speed motor)

Wiper arm puller

Socket wrench set

Screwdriver

Electrical tape

Step 1: Disconnect the Battery

To prevent any electrical hazards, disconnect the negative terminal of the battery before starting any work on the wiper system.

Step 2: Remove the Windshield Cowl

The windshield cowl is a plastic cover located at the base of the windshield. To remove it, unclip the snaps along the edges and pull it straight up.

Step 3: Remove the Wiper Blades

Using a wiper arm puller, detach the wiper blades from the wiper arms. Simply hook the puller over the base of the blade and pry it off the arm.

Step 4: Remove the Wiper Arms

Locate the bolts that secure the wiper arms to the linkage. Use a socket wrench to remove these bolts, taking care not to damage the linkage.

Step 5: Remove the Linkage (Optional)

If upgrading to a heavy-duty or variable-speed wiper motor, it may be necessary to remove the old linkage. Unbolt the linkage from the wiper motor and pull it out.

Step 6: Install the New Linkage (Optional)

If replacing the linkage, insert the new linkage into the wiper motor and secure it with the bolts.

Step 7: Install the New Wiper Motor (Optional)

If upgrading to a new wiper motor, disconnect the electrical connector from the old motor and remove it from the vehicle. Install the new motor and reconnect the electrical connector.

Step 8: Install the Wiper Arms

Attach the wiper arms to the linkage by inserting them into the slots and tightening the bolts. Ensure that the arms are facing the correct direction.

Step 9: Install the Wiper Blades

Snap the new wiper blades onto the wiper arms until they are securely attached.

Step 10: Reinstall the Windshield Cowl

Align the windshield cowl with the base of the windshield and clip it back into place.

Step 11: Connect the Battery

Reconnect the negative terminal of the battery and test the wipers.

Conclusion

Upgrading the wiper system on a Jeep YJ is a straightforward process that can greatly improve visibility in adverse weather conditions. By following the steps outlined in this article, you can ensure a safe and comfortable driving experience in your YJ. Remember to periodically inspect and maintain the wiper system to keep it functioning optimally.
