Dodge D350 Wiper Motor Guide for 1981-1988 Models
Everything you need to know before replacing the wiper motor on your classic Dodge D350 truck.
- Wiper failure is a critical safety issue. Do not drive in rain or snow with non-functional wipers.
- Before buying a motor, check if the motor runs but the arms don't move. If so, you may only need to replace inexpensive linkage bushings.
- New aftermarket motors from brands like Cardone or WAI Global are the most common and reliable replacement option for this truck.
- Replacement is a DIY-friendly task that requires removing the cowl panel to access the motor assembly.
Is Your D350 Wiper Motor Failing?
On these classic Dodge trucks, wiper motor failure is a common issue due to age. The internal components wear out, and electrical connections can fail. Watch for these signs:
- Wipers Don't Move: The most obvious sign is when the wipers don't move at all, but you might hear a humming sound from the motor. This points to a seized motor or an internal electrical problem.
- Only One Speed Works: If your wipers only work on the high-speed setting, the internal resistor that controls the lower speeds has likely failed.
- Slow or Erratic Movement: Wipers that struggle to move, pause randomly, or move at an inconsistent speed suggest the motor is getting weak or the internal gears are worn.
- Wipers Won't Park Correctly: If the wipers stop in the middle of the windshield when you turn them off, the 'park' switch inside the motor assembly is broken.
- Blown Fuses: A motor that is failing can draw too much electricity, causing the fuse to blow repeatedly.
Check the Bushings First!
Sometimes, the motor is fine, but the plastic linkage bushings have disintegrated. If you can hear the motor running but the arms don't move, the linkage has likely detached from the motor. These bushings are inexpensive and much easier to replace than the entire motor.
Choosing a New Aftermarket Wiper Motor
For a truck from the 1980s, finding a new OEM (Original Equipment Manufacturer) part from Dodge is nearly impossible. The market is almost entirely new aftermarket or remanufactured parts. Both are good options for keeping your D350 on the road.
Brand Options: Cardone vs. WAI Global
Your main choices for a new aftermarket motor will likely be Cardone and WAI Global. Both are established brands in the automotive electrical parts world.
- Cardone: Cardone has a long history of both remanufacturing parts and producing new ones. They often reverse-engineer original parts to identify and correct weaknesses, such as using stronger materials for internal gears to prevent stripping. While some reviews mention receiving a defective unit initially, the replacement part generally works well.
- WAI Global: WAI Global is well-regarded for its electrical components, applying experience from building starters and alternators to their wiper motors. They are known for consistent performance and are a common choice for professional technicians. Reviews often praise their easy installation and reliable operation.
New vs. Remanufactured: For this part, a 'new' aftermarket motor is often preferred. It means all components, including the internal electronics and gears, are fresh. A 'remanufactured' motor has been rebuilt, and while it's a cost-effective option, some online discussions show concern about the quality of the rebuilt internal park switch. Given the small price difference, a new unit provides extra peace of mind.

Frequently Asked Questions
Are there any recalls for the 1981-1988 D350 wiper motor?
No, searches of the National Highway Traffic Safety Administration (NHTSA) database did not show any wiper motor recalls specifically for the 1981-1988 Dodge D350 model years. Recalls found were for much newer model year Ram trucks.
How hard is it to replace the D350 wiper motor myself?
It's a manageable job for a DIYer. The process involves removing the wiper arms, taking off the plastic cowl panel below the windshield, and then unbolting the motor and linkage assembly. You'll need basic hand tools like a socket set and screwdrivers. A special wiper arm puller tool can be very helpful to avoid damaging the arms.
Do I need to replace the wiper linkage at the same time?
Not necessarily, but you should inspect it. While the motor and linkage assembly is out, check the plastic bushings at all the pivot points. If they are cracked, brittle, or missing, replace them. It's an inexpensive part that prevents future failure.
What is a 'park switch' and why does it fail?
The park switch is an internal component of the wiper motor assembly that tells the motor when the wipers have reached the bottom of the windshield, signaling it to stop. When it fails, the motor doesn't get the 'stop' signal, and the wipers will either keep running or stop in a random position when you turn the switch off. This is a common failure point due to age and wear on the electrical contacts.
