Chrysler LeBaron Windshield Washer Pump Replacement Guide (1977-1986)
Everything a LeBaron owner needs to know to diagnose and replace a faulty windshield washer pump.
- A silent pump motor is the clearest sign of failure; listen for a buzzing sound when the switch is pressed.
- Replacement is a simple, DIY-friendly job that takes less than an hour with basic tools.
- New aftermarket parts from brands like ACDelco and Trico are the most practical and affordable solution for these classic vehicles.
- Before replacing the pump, always check for simple fixes like clogged nozzles, cracked hoses, or a blown fuse.
Is Your LeBaron's Washer Pump Failing?
On a classic car like the 1977-1986 LeBaron, the washer system is simple. Troubleshooting problems is usually straightforward. If your washers aren't working, the pump is a common suspect. Here are the signs of a bad washer pump.
- No Sound, No Spray: You activate the switch and hear nothing. If the washer fluid tank is full, a silent pump motor is the most common sign of failure. The pump is either broken or not getting power.
- Motor Runs, But No Fluid: You can hear the pump motor whirring, but nothing sprays on the windshield. This can mean the pump's internal parts have failed, but you should first check for cracked hoses or a clogged filter at the pump's intake.
- Weak or Uneven Spray: The fluid barely reaches the windshield or sprays unevenly. While often caused by clogged nozzles, a dying pump can lose pressure and struggle to spray effectively.
Pro Tip: Before buying a new pump, do a quick check. Have a friend activate the washer switch while you listen near the fluid reservoir. If you hear the motor, the problem might be a clog, not the pump. Use a small pin to clear any debris from the washer nozzles on the hood.
Choosing the Right Aftermarket Pump
For a vehicle from this era, finding a new Original Equipment (OEM) Mopar pump is nearly impossible. Aftermarket parts are the only practical choice. They are affordable, widely available, and designed to fit and function like the original. The key is choosing a reputable brand.
Brand Quality Tiers
- Premium Aftermarket (ACDelco): While known as a GM parts supplier, ACDelco makes high-quality replacement parts for many brands, including Chrysler. Their pumps are known for reliability and durability, often meeting or exceeding original specifications. An ACDelco pump is a top-tier choice for your LeBaron.
- Standard Aftermarket (Trico): Trico is a well-known brand in wiper and washer systems. Their pumps are designed to be easy-to-install, reliable replacements. They offer a great balance of quality and value, making them a very common and dependable choice for this repair.
Cost to Replace a LeBaron Washer Pump
Replacing the washer pump is one of the more affordable repairs you can make. The parts are inexpensive, and if you do it yourself, you can save a lot on labor.
| Part or Service | Estimated Cost |
|---|---|
| New Aftermarket Pump | $24.64 - $35.65 |
| Shop Labor | $98 - $143 |
| DIY Total | $24.64 - $35.65 |

Don't Forget the Grommet: The pump seals to the reservoir with a rubber grommet. Old grommets get hard and brittle and will leak. Most new pumps include a new grommet, but always confirm. Never reuse the old one.
Frequently Asked Questions (FAQ)
Is the washer pump hard to replace myself?
No, this is a great DIY job for beginners. The pump is usually pushed into the side of the washer fluid reservoir, located under the hood. The job involves siphoning out the old fluid, pulling out the old pump, pushing in the new one, connecting a wire, and refilling the tank. It typically takes less than an hour with basic tools.
Are there any recalls for the LeBaron washer pump?
No. Searches of the National Highway Traffic Safety Administration (NHTSA) database show no recalls or specific technical service bulletins (TSBs) for the windshield washer pump on the 1977-1986 Chrysler LeBaron.
My new pump is installed, but it's still not working. What now?
First, check the fuse for the washer system in your car's fuse box. If the fuse is good, the problem could be the switch in the steering column or a break in the wiring going to the pump. Use a multimeter to see if power is getting to the pump's connector when the switch is activated.
Is the pump the same for all LeBaron models from 1977-1986?
For the most part, yes. The 1977-1981 LeBaron was an M-body, while the 1982-1986 model was a K-car. However, aftermarket manufacturers often use a single universal-style replacement pump that fits a wide range of Chrysler vehicles from this period, including both LeBaron generations. Always confirm the fitment for your specific year before purchasing.
Can I just use water in the reservoir?
It is not recommended. Proper windshield washer fluid contains solvents to clean grime and bug splatters. It also contains antifreeze agents to prevent the fluid, pump, and lines from freezing and cracking in cold weather. Using only water can lead to damage and less effective cleaning.
Technical Specifications
Voltage: 12V. Mounts directly to the windshield washer fluid reservoir. Typically includes a new rubber grommet for sealing.
