Keep your classic Dodge D150's windshield clear by understanding common wiper motor problems and choosing the right replacement.
- Before buying a new motor, check for broken plastic wiper linkage bushings, a very common and cheap fix for this truck.
- Symptoms like single-speed operation or incorrect parking almost always point to a bad motor, not the switch.
- Aftermarket brands like Cardone and WAI Global are affordable options, but be aware that receiving a defective unit is possible.
- Replacement is a DIY-friendly job that usually takes less than two hours.
Symptoms of a Failing Dodge D150 Wiper Motor
When a wiper motor starts to fail, it usually gives a few warning signs. Ignoring them can leave you without wipers in bad weather, which is a serious safety risk. Here’s what to look for:
- Slow or Jerky Wipers: The wipers move slower than they used to, even on the high-speed setting. They might also move in a hesitant or jerky way.
- Wipers Only Work on One Speed: You might find that only the high-speed setting works, or there's no difference between low and high. This often points to a problem with the motor's internal electrical parts.
- Wipers Won't Park Correctly: When you turn the wipers off, they should return to their resting position at the bottom of the windshield. If they stop in the middle of the glass, the motor's internal park switch has likely failed.
- No Movement at All: The most obvious symptom is when the wipers don't move at all. You might hear a humming or buzzing sound from the motor, which means it's getting power but the internal gears may be stripped or jammed. If you hear nothing, the motor may be completely burned out or not receiving power. 🎬 Watch: How to diagnose a non-functioning wiper motor
Check This Before You Buy! A Common D150 Wiper Issue
On these first-generation Dodge trucks, a very common problem is the failure of small plastic bushings in the wiper linkage. These bushings connect the metal arms of the linkage together. Over time, they become brittle and break. When this happens, you will hear the wiper motor running, but the wiper arms won't move, or only one will move. This is a much cheaper and easier fix than replacing the entire motor. Always inspect the wiper linkage for broken bushings before ordering a new motor.

For a vehicle of this age, new OEM parts from Mopar are likely unavailable or extremely expensive. Aftermarket parts offer a practical and affordable solution. The two main brands you will find are Cardone and WAI Global.
Brand Quality Assessment:
- Cardone: Cardone is a well-known brand that offers both new and remanufactured parts. They have been in the wiper motor business for a long time. However, customer reviews are often mixed. Some users report receiving parts that are defective right out of the box, sometimes due to internal grounding issues. While many have success with the part, be prepared for the possibility of needing to exchange a faulty unit.
- WAI Global: WAI Global specializes in new automotive electrical components and has a good reputation for quality in parts like alternators and starters. Their new wiper motors are generally well-regarded for fitting correctly and operating quietly. While less common than with other brands, some reviews still mention receiving a defective part initially.
When replacing the motor, it's also a good time to inspect the wiper linkage arms for excessive rust or play, and to replace the plastic linkage bushings as preventative maintenance.

Frequently Asked Questions (FAQ)
Is replacing the wiper motor a difficult job?
No, for most DIYers, this is a straightforward job. It requires basic hand tools to remove the wiper arms and the cowl panel to access the motor. The entire process typically takes about 1 to 2 hours.
How do I know if it's the motor or the wiper switch?
A faulty switch can cause similar problems, like intermittent operation. However, if the wipers only work on one speed or won't park correctly, the issue is almost always the motor's internal components. If you hear the motor humming but the wipers don't move, the problem is likely the linkage bushings, not the switch.
Are all wiper motors from 1977 to 1988 the same?
There were some design changes over this period. For example, motors from the early 1990s are physically smaller than those from the mid-1980s but can be adapted to fit. It is critical to enter your truck's exact year when ordering to ensure you get a direct-fit replacement 🎬 Watch: How to adapt a newer motor to your truck with the correct electrical connector.
