A Note on Vehicle Years
Symptoms of a Failing Wiper Motor
A wiper motor usually gives warning signs before it fails completely. If you notice any of these issues with your Avenger, the motor is the likely cause.
- Slow or Lagging Wipers: Even on the highest setting, the wipers move sluggishly. This can be due to internal wear in the motor or a failing electrical component.
- Wipers Won't Park: When you turn the wipers off, they stop randomly on the windshield instead of returning to the bottom. This points directly to a bad park switch inside the motor assembly.
- Only One Speed Works: The wipers may only function on the high-speed setting, which indicates a problem with the motor's internal speed controls.
- No Movement at All: If the wipers don't move, and you've already checked the fuse, the motor has likely burned out.
- Grinding or Humming Noises: Unusual sounds from the cowl area when the wipers are on suggest worn or broken gears inside the motor.
Choosing a New Aftermarket Wiper Motor
For a vehicle of this age, a new aftermarket motor is a practical and widely available choice. The original OEM Mopar part (MR387975) may be difficult to find new.
Cardone is a common aftermarket brand available for your Avenger. They offer both new parts (under the "Cardone Select" line) and remanufactured ones. Cardone states that their new motors are often reverse-engineered to fix original design flaws, such as using more durable materials for the internal gears. While many users have success with these parts, some reviews mention receiving a defective unit out of the box. However, they typically come with a warranty to protect against such issues.

Frequently Asked Questions (FAQ)
Is replacing the wiper motor a DIY job?
Yes, for most home mechanics with basic tools, this is a manageable job. The process involves removing the wiper arms and the plastic cowl cover to access the motor. The most difficult step can be removing wiper arms that are seized onto their posts. A special wiper arm puller tool can be helpful. The entire job should take about 1 to 2 hours.
Do I need to replace the wiper linkage too?
Usually, no. You can typically unbolt the motor from the linkage assembly and replace only the motor. However, while you have it apart, it's a good idea to inspect the plastic bushings on the linkage arms. If they are cracked or broken, the linkage should be replaced at the same time to prevent sloppy wiper movement.
My wipers don't work. How do I know it's the motor?
First, always check the fuse for the wiper system in your fuse box. A blown fuse is a simple and cheap fix. If the fuse is good, the motor is the next most likely culprit. You can also listen for a faint humming sound from the motor when the wipers are turned on; if you hear a hum but see no movement, the motor is getting power but has failed internally.
Are there any recalls on the 1998-2000 Avenger wiper motor?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database did not find any safety recalls or Technical Service Bulletins (TSBs) specifically for the windshield wiper motor on the 1998-2000 Dodge Avenger.
