- Aftermarket brands like Trico offer a quality, direct-fit replacement for much less than OEM parts.
Is Your Transporter's Washer Pump Failing?
A faulty windshield washer pump is more than an annoyance; it's a safety issue. A dirty windshield can block your view of the road. For Transporter owners, especially those who use their vans for work or travel, keeping the windshield clear is critical. Common symptoms of a failing pump are easy to spot and usually point directly to the pump itself or a related issue like a blown fuse or clogged line.
Symptoms of a Bad Windshield Washer Pump
- No Fluid Spraying: When you activate the washer, the wipers move, but no fluid comes out. You may or may not hear the pump motor humming. If you hear nothing, the pump motor is likely dead or not receiving power.
- Weak or Uneven Spray: The fluid barely reaches the windshield or comes out in a weak dribble. This can indicate a dying pump motor that can no longer generate enough pressure.
- Pump Works Intermittently: The spray works sometimes and not others, suggesting an electrical issue with the pump or a motor that is about to fail completely.
- Visible Fluid Leaks: You might see blue, green, or orange fluid puddling under the front of your van, especially near the wheel well where the reservoir is located. Leaks often come from a cracked pump housing or a dried-out rubber grommet where the pump enters the reservoir.
First, Check the Fuse
Before you replace the pump, always check the fuse first. A blown fuse is a common issue, especially after winter when fluid may have frozen in the lines, straining the pump motor. On a T5 Transporter, the fuse box is often located in the engine bay near the battery. A simple fuse replacement could save you the cost and effort of replacing the entire pump.
Choosing the Right Aftermarket Pump
When replacing the washer pump on your Transporter, you don't need to pay for an expensive OEM (Original Equipment Manufacturer) part from the dealer. Aftermarket parts offer comparable quality for a fraction of the price. The key is to choose a reputable brand.
Trico: Trico is a well-known brand in windshield wiper and washer systems, founded in 1917. Their aftermarket washer pumps are designed as direct-fit replacements, meaning they install without any modifications. They are built to be a reliable and cost-effective alternative to OEM parts, making them a solid choice for a DIY repair.
Cost of a New Windshield Washer Pump (2006-2012 VW Transporter)
| Part Type | Estimated Cost |
|---|---|
| New OEM | $75 - $115 |
| New Aftermarket (Trico) | $37.72 - $57.11 |
| Shop Labor | $60 - $120 |
Pro Tip: Replace the Grommet
The small rubber seal, or grommet, where the pump pushes into the reservoir tank can become hard and brittle over time. This is a common source of leaks. Since you're already replacing the pump, it's smart to replace the grommet at the same time. It's an inexpensive part that provides peace of mind against future leaks.
Frequently Asked Questions (FAQ)
Is replacing the washer pump a DIY job?
Yes, for most people with basic tools, this is a very manageable DIY repair. Accessing the pump usually involves turning the front wheel and removing a few screws from the plastic wheel well liner. The pump itself just pulls out of the reservoir, and the electrical connector and hoses are simple to detach. The entire job can often be done in under an hour.
Do I need any special tools?
No special tools are required. A basic set of screwdrivers (including Torx bits for some VW screws), a small container to catch any remaining washer fluid, and perhaps a pair of pliers are all you should need.
My Transporter has a rear washer. Is the pump different?
The pump itself is often the same, but it will have two outlets—one for the front windshield and one for the rear. When installing the new pump, make sure you connect the hoses to the correct outlets to ensure fluid goes to the right place. It's a good idea to mark which hose is which before you disconnect the old pump.
Are there any recalls for the VW Transporter washer pump?
There are no specific recalls for the windshield washer pump on the 2006-2012 Volkswagen Transporter in the North American market. The Transporter was not officially sold in the United States, so it is not listed in the NHTSA (National Highway Traffic Safety Administration) database for recalls. Any recalls found would likely be for other Volkswagen models or from other regions.
