1998-2003 Dodge Durango Wiper Motor: The Water Intrusion Recall and 4-Pin vs. 5-Pin Guide

A Critical Compatibility Warning: 4-Pin vs. 5-Pin Connectors

Known Issues: Safety Recall for Water Intrusion

A major issue affects these wiper motors, particularly on later models. In May 2004, DaimlerChrysler issued a safety recall (NHTSA Campaign ID: 04V216000, also known as recall D22) for this problem.

The recall states that the original windshield wiper motor was susceptible to water intrusion. Water could leak into the motor housing, causing internal corrosion and leading to partial or complete failure of the front wipers. This could suddenly reduce driver visibility and potentially cause a crash.

The recall primarily targeted late-2002 and 2003 Dodge Durango models but also included some 2000-2002 models that may have had an earlier service replacement motor installed. The fix was for dealers to replace the entire front windshield wiper motor assembly with a revised part that included a better water shield.

This is critical information for anyone buying a used part. A motor from a recalled vehicle that was never updated carries a significant risk of premature failure due to this design flaw.

Symptoms of a Failing Wiper Motor

When your Durango's wiper motor begins to fail, it will usually give you several warning signs. Here are the most common symptoms to watch for:

• Wipers Don't Move at All: You turn the switch on and nothing happens. You might hear a faint humming or clicking from the motor area, or complete silence.
• Wipers Only Work on One Speed: Often, the motor will only function on the highest speed setting. This typically points to a failure in the motor's internal circuitry or resistor that controls lower speeds.
• Slow or Erratic Operation: The wipers may move much slower than usual, or they might speed up and slow down randomly. This can be caused by internal wear or the early stages of water-induced corrosion.
• Wipers Won't Park Correctly: When you turn the wipers off, they stop in the middle of the windshield instead of returning to their resting position. This indicates a failure of the internal park switch mechanism.
• Wipers Won't Turn Off: In some cases, the wipers may continue to run even when the switch is in the 'Off' position. This can be caused by a faulty park circuit or a stuck relay.
• Grinding or Buzzing Noises: Any unusual noises from the base of the windshield when the wipers are on suggest worn or damaged gears inside the motor assembly.

Simple Diagnosis Steps

Before you condemn the motor, perform these simple checks:

1. Check the Fuse: The first and easiest step is to check the fuse for the wiper system in your vehicle's fuse box. A blown fuse is a simple fix.
2. Check the Relay: The wiper system uses a relay, which can sometimes fail and cause symptoms like the wipers not turning off. Swapping it with a known good relay can be a quick diagnostic test.
3. Listen to the Motor: Have a friend operate the wiper switch while you listen near the cowl panel at the base of the windshield. If you hear the motor humming or trying to work but the arms don't move, the problem could be a stripped gear inside or a disconnected linkage. If you hear nothing, it points toward an electrical issue or a dead motor.
4. Inspect the Linkage: Sometimes the motor is fine, but the linkage arms that connect the motor to the wiper pivots have popped off or broken.

Buying a Used Windshield Wiper Motor

A used OEM wiper motor can be a reliable and cost-effective solution. Here’s what to look for:

• Verify the Connector: This is the most important step. Confirm if you need the 4-pin (1998-2000) or 5-pin (2001-2003) version. Do not trust a seller's generic description; ask for a photo of the connector or provide your vehicle's year to ensure a match.
• Ask About the Recall: For a 2001-2003 motor, ask if it is the updated part from the recall. While difficult to verify visually, sellers specializing in these vehicles may be aware of the issue. Prefer motors from later-production 2003 vehicles or even 2004 Dakotas (which used a similar updated part) if possible.
• Inspect the Connector Pins: Look for any signs of green or white corrosion, or melted plastic around the pins. This is a clear sign of water damage or an electrical short, and the part should be rejected.
• Check the Gear Housing: Inspect the plastic or metal casing of the motor for any cracks or signs of being tampered with.
• Why Used OEM?: A used original equipment (Mopar) motor that is clean and from a low-mileage vehicle is often a better choice than a cheap, new aftermarket part. OEM parts are designed for perfect fitment and electrical compatibility, reducing the risk of the strange electrical gremlins that can sometimes appear with non-OEM electronics.

Cost of Replacement

Here is an estimated breakdown of what you can expect to pay for a replacement windshield wiper motor for a 1998-2003 Dodge Durango.

Replacement Overview

Replacing the wiper motor on a first-generation Durango is a manageable DIY job for someone with basic tools and mechanical experience.

• Difficulty: 2.5 out of 5
• Estimated Time: 1-1.5 hours

General Steps:

1. Disconnect the negative battery terminal.
2. Mark the position of the wiper blades on the windshield with tape to ensure correct reinstallation.
3. Remove the nuts holding the wiper arms to the pivot shafts and carefully pry the arms off. They can be stuck on tight.
4. Remove the plastic cowl panel at the base of the windshield. This is usually held on by several plastic clips and possibly a few screws.
5. Disconnect the electrical connector from the wiper motor.
6. Unbolt the wiper motor and linkage assembly (usually three bolts).
7. Remove the assembly from the vehicle. You may need to separate the motor from the linkage on a workbench.
8. Installation is the reverse of removal. Before putting the cowl and wiper arms back on, briefly reconnect the battery and test the motor to ensure it works and is in the 'park' position.
