Dodge B250 Wiper Motor Guide (1981-1988): Symptoms and Replacement
Don't get caught in the rain; here’s what to know when your 1981-1988 B250's wipers quit.
- Before replacing the motor, always inspect the small, inexpensive plastic wiper linkage bushings; they are a very common failure point on these vans.
- Symptoms like slow operation, only one speed working, or incorrect parking are clear signs of a failing motor.
- Aftermarket brands like Cardone (New and Remanufactured) and WAI Global (New) are the most common and reliable choices for this vehicle.
- Replacement is a DIY-friendly job that requires removing the cowl panel at the base of the windshield for access.
Is Your Wiper Motor Failing?
On a classic Dodge B250, the wiper system is straightforward. When it fails, the signs are usually obvious. If you're experiencing any of the following, your wiper motor is likely wearing out.
- Slow or Erratic Wipers: The wipers move much slower than they used to, even on the high setting. They might also stutter or move unsteadily across the glass.
- Only One Speed Works: You might find that only your high-speed setting works, while the slower, intermittent settings have stopped functioning.
- Wipers Don'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 points to a failure in the motor's internal park switch.
- No Movement at All: You turn the switch and hear a faint humming or clicking sound from the motor, but the wipers don't move. If you hear nothing at all, you should check your fuse first.
Before You Buy a Motor: Check Your Wiper Linkage Bushings!
On these 1980s Dodge Vans, a very common point of failure is not the motor itself, but the small plastic bushings that connect the motor to the wiper linkage arms. Over decades, these bushings become brittle and crumble. When they break, the motor arm disconnects from the linkage. You will hear the motor running, but the wipers won't move at all, or one wiper may move while the other doesn't. These bushings are very inexpensive and should always be inspected before spending money on a new motor.
Choosing a New Aftermarket Wiper Motor
For a vehicle of this age, finding a new OEM Mopar part is nearly impossible. The market is served by aftermarket brands that offer direct-fit replacements. The two most common brands you will find are Cardone and WAI Global.
- Cardone: Cardone is a well-established aftermarket company. They offer both brand-new and remanufactured wiper motors. Their new parts are built to match original specifications, while their remanufactured units are rebuilt original parts, which can sometimes be a good balance of quality and cost. Both are generally considered reliable, direct-fit options.
- WAI Global: WAI is another major aftermarket supplier specializing in electrical components. They typically offer new wiper motors. Owner reviews are often mixed, as is common with many aftermarket brands, but they are a widely available and cost-effective solution.
Pro Tip: There is little practical difference in quality between these two mainstream aftermarket brands for a simple part like this. Your choice will likely come down to price and availability. Both new and remanufactured Cardone units and new WAI Global motors are designed to restore original function.
What Will It Cost?
The total cost depends on whether you do the work yourself or hire a mechanic. Given the age of the B250, parts are affordable.
| Part/Service | Estimated Cost |
|---|---|
| New Aftermarket Motor (Cardone, WAI Global) | $101.48 - $192.99 |
| Used OEM Motor (from a salvage yard or eBay) | $35 - $100 |
| Shop Labor to Install | $120 - $200 |
| Total Professional Replacement | $220 - $400 |
Frequently Asked Questions (FAQ)
How do I know if it's just a blown fuse?
If your wipers stop working completely and you don't hear any sound from the motor area when you activate the switch, a blown fuse is a possibility. The fuse box is located in the glove compartment. However, if the wipers are slow, only work on one speed, or won't park, the problem is almost certainly the motor itself, not the fuse.
How hard is it to replace the wiper motor myself?
For a DIY mechanic with basic tools, this is a manageable job. The main challenge is accessing the motor. You will need to remove the plastic cowl panel located at the base of the windshield. Once the cowl is off, you can see the entire wiper linkage assembly. The motor is held onto the assembly with a few bolts. The process involves removing the wiper arms, taking off the cowl, disconnecting the motor's electrical plug and linkage arm, swapping the motor, and then reassembling everything.
What's the difference between a 'new' and 'remanufactured' motor?
A 'new' aftermarket motor from a brand like WAI Global or Cardone is a complete, newly manufactured part. A 'remanufactured' motor, typically from Cardone, is an original OEM motor that has been taken apart, cleaned, inspected, and had any worn or failed components replaced with new ones. For a simple part on an older vehicle, both are excellent options.
Do I need any special tools for the job?
No highly specialized tools are required. You will need a basic socket set, screwdrivers, and possibly a trim tool to help remove the cowl without breaking any clips. A key step after installing the new motor is to connect it electrically and run it once to let it return to its 'park' position *before* you attach the wiper linkage arm. This ensures the wipers will park correctly once everything is reinstalled.
