1. Identify the Source:
* Visual Inspection: Start by looking under the passenger side of the Windstar, focusing on the area where the leak appears. Look for wet spots, puddles, or trails of washer fluid. Try to trace the source back up. A flashlight will be helpful.
* Reservoir: Carefully inspect the washer fluid reservoir itself. Look for cracks, holes, or loose connections. The reservoir's cap might also be leaking. Try tightening it.
* Hoses: Follow the washer fluid hoses leading from the reservoir. Look for cracks, kinks, or loose clamps. Pay close attention to where the hoses connect to the reservoir and the spray nozzles. These are common points of failure. A small crack might only leak when the pump is active.
* Pump: The washer fluid pump is usually located near the reservoir. Check its connections and look for any signs of leakage around the pump itself. It's less likely to be the source of a leak directly under the vehicle, unless it's severely cracked or corroded.
2. Repairing the Leak:
The repair will depend on what's causing the leak:
* Cracked Reservoir: If the reservoir is cracked, it needs to be replaced. This is usually the most involved repair and may require some dexterity to remove and install the new reservoir.
* Leaking Hose: If a hose is cracked or leaking at a connection, you can often repair it with a hose clamp (if the hose itself is intact) or replace the section of the hose. You'll need to get the correct size of hose and clamps.
* Loose Hose Connection: Tighten any loose clamps on the hoses. If the hose is slipping off the nipple, you might need a new hose or to carefully secure it.
* Pump Leakage: If the pump is leaking, it likely needs replacement. This can be a moderately difficult repair.
3. Repair Procedure (General):
These steps are a general guide and may vary slightly depending on your specific Windstar year and model:
* Gather Tools: You'll likely need screwdrivers, pliers, possibly a wrench, new hose, clamps, and a new reservoir if needed. Having jack stands and a jack is recommended to get better access.
* Access the Reservoir and Hoses: You may need to remove some underbody panels or wheel well liners to access the components fully.
* Repair or Replace: Once you've identified the leak, repair or replace the damaged component.
* Refill: After completing the repair, refill the washer fluid reservoir.
* Test: Turn on the windshield wipers and check for leaks.
Important Considerations:
* Safety First: Always disconnect the battery's negative terminal before working near electrical components. Use jack stands for safety when working under the vehicle.
* Parts: Obtain replacement parts from a reputable auto parts store. Ensure you get the correct parts for your specific year and model of Ford Windstar.
* DIY vs. Professional: If you're not comfortable working on your car, it's best to take it to a qualified mechanic. Replacing the reservoir can be challenging if you lack experience.
By systematically checking each component, you should be able to pinpoint and fix the washer fluid leak under your Ford Windstar. Remember to take pictures before disassembling anything to help with reassembly.
