Here's a general outline; however, specific details may vary slightly depending on your exact Windstar model and trim level. It's strongly recommended you consult a repair manual specific to your vehicle's year and model. A Haynes or Chilton manual will provide detailed diagrams and instructions.
Steps:
1. Locate the Pump: The washer pump is usually located in the wheel well, behind the bumper, or sometimes under the hood, near the washer fluid reservoir. Consult your repair manual for the precise location.
2. Access the Pump: This often involves removing some under-hood components or parts of the wheel liner or splash guard to gain access to the pump. You may need to use various tools like screwdrivers, sockets, and possibly a plastic trim removal tool to avoid damaging the clips.
3. Disconnect the Electrical Connector: Carefully disconnect the electrical connector from the pump. Take a picture or make a note of how it's connected before disconnecting to ensure proper reassembly.
4. Disconnect the Washer Lines: There are usually two lines connected to the pump: one for the front windshield and one for the rear (if equipped). Carefully disconnect these lines. These lines might be clamped on, so you'll need pliers or a clamp removal tool. Have rags or containers handy to catch any spilled fluid.
5. Remove the Pump: Once the electrical connector and lines are disconnected, you should be able to remove the pump from its mounting location. This might involve removing bolts or clips.
6. Install the New Pump: Carefully install the new pump, ensuring it's seated correctly in its mounting location. Reconnect the washer lines securely, using clamps if necessary.
7. Reconnect the Electrical Connector: Reconnect the electrical connector, ensuring a snug and secure fit.
8. Reassemble: Put everything back together, reversing the steps you took to access the pump.
9. Test: Reconnect the negative battery terminal. Fill the washer fluid reservoir and test the washer system to ensure the new pump is working correctly.
Important Considerations:
* Repair Manual: Using a repair manual is highly recommended. It provides specific instructions and diagrams tailored to your vehicle, which is crucial to avoid damage and ensure proper installation.
* Tools: Gather the necessary tools beforehand to avoid interruptions.
* Safety: Work in a well-lit and ventilated area. Always wear safety glasses.
* Fluid Type: Use the correct type of windshield washer fluid for your climate.
If you're uncomfortable performing this repair yourself, it's best to take your Windstar to a qualified mechanic. The cost of a professional repair might be less than the cost of a damaged part or an incorrectly installed pump.
