2000-2002 Hyundai Accent Rear Wiper Motor: Failure Symptoms & Replacement Guide

Known Issues & Compatibility Warnings for 2000-2002 Hyundai Accent

The most common issue reported by owners is failure after attempting to use the wiper when it's frozen to the glass. Activating the motor when the arm is stuck can strip the internal gears or burn out the motor itself. Another point of failure can be the splines on the output shaft where the wiper arm mounts; if the retaining nut is loose or the arm is forcibly moved, the splines can strip, causing the motor to run without the arm moving.

Symptoms of a Failing Rear Wiper Motor

A failing rear wiper motor often gives warning signs before it stops working completely. Here’s what to look and listen for:

• Slow or Weak Movement: The wiper arm moves sluggishly across the glass and may struggle to clear water effectively. This can be an early sign of a worn-out motor or a seized pivot shaft.
• Wiper Doesn't Move, But You Hear the Motor: If you can hear a humming or running sound from the rear hatch when you activate the switch, but the arm doesn't move, the problem is likely stripped gears inside the motor assembly or stripped splines on the wiper arm itself.
• No Movement or Sound: If there is no response at all when you flip the switch, the issue could be the motor, a blown fuse, a bad switch, or broken wiring in the flexible harness between the body and the hatch.
• Intermittent Operation: The wiper works sporadically, sometimes requiring a tap on the hatch to start. This often points to loose internal connections or worn brushes inside the motor.
• Wiper Won't Park Correctly: The blade stops in the middle of the glass or at a random position instead of returning to its designated resting place. This indicates a problem with the motor's internal park switch.
• Loud or Unusual Noises: Grinding, clicking, or chattering sounds from the rear hatch area during operation suggest mechanical wear or damage to the internal gears.

Buying a Used Rear Wiper Motor

A used OEM rear wiper motor is a cost-effective and reliable alternative to expensive new parts. Since these motors are not a high-wear item on most vehicles, a good-quality recycled part can provide many years of service. Here's what to check before you buy:

• Verify the Part Number: The most reliable way to ensure compatibility is to match the OEM part number. For this Accent, you'll be looking for 98700-25000 or 98700-25050. These two numbers are often interchangeable for this model range.
• Inspect the Output Shaft: Look closely at the splined metal shaft where the wiper arm attaches. The splines should be clean, sharp, and free of stripping or damage. A stripped shaft is a major red flag.
• Check the Electrical Connector: The connector pins should be straight, clean, and free of any green or white corrosion. The plastic housing should not be cracked or brittle.
• Ask About the Source Vehicle's Mileage: While not always possible, lower mileage is generally better. However, function is more important than mileage for this part. A motor from a 150,000-mile car that works perfectly is a better buy than one from a 50,000-mile car that is damaged.
• Look for Physical Damage: Inspect the motor's casing for any cracks, signs of being opened, or heavy corrosion, which could indicate water intrusion.

Replacement Overview

Replacing the rear wiper motor on a 2000-2002 Accent is a straightforward job suitable for a DIYer with basic tools. The entire process typically takes less than an hour.

1. Disconnect the Battery: As a safety precaution, disconnect the negative battery terminal.
2. Remove the Wiper Arm: Lift the plastic cap at the base of the wiper arm and remove the retaining nut (typically 13mm). The arm may be stuck on the splined shaft; gently wiggle it back and forth while pulling to release it.
3. Remove the Interior Trim Panel: The large plastic panel on the inside of the rear hatch must be removed. It is held in by a series of clips. Start at one edge and carefully pry the panel away from the hatch to release the clips.
4. Disconnect and Unbolt the Motor: With the trim removed, you will see the wiper motor. Disconnect the electrical harness. Remove the bolts (usually three 10mm bolts) securing the motor assembly to the hatch.
5. Install the New Motor: Installation is the reverse of removal. Mount the new motor, reconnect the electrical harness, and reinstall the interior trim panel. Before putting the wiper arm back on, briefly reconnect the battery and turn on the rear wiper to allow the motor to cycle to its 'park' position. Then turn it off.
6. Reinstall the Wiper Arm: Place the wiper arm back onto the motor shaft in its correct parked position at the bottom of the glass and tighten the retaining nut. Reconnect the battery if you haven't already.
