Here's a step-by-step guide:
1. Gather your materials. You'll need a replacement windshield wiper blade for the driver's and passenger's side. You can find these at any auto parts store or online. Look for the blades that are specifically designed for the 2000 Ford Windstar.
2. Preparation: Before starting the process, make sure your car's engine is off.
3. Locate the windshield wiper arms: The wiper arms are the metal arms that hold the wiper blades in place. They're located on the front of your car, just above the windshield.
4. Lift one of the wiper arms. The blades should be folded against the windshield towards the driver. Lift one of the wiper arms up until it is perpendicular to the windshield.
5. Remove the old wiper blade: There is usually a small release button or tab on the wiper arm. Press this button and pull the old wiper blade straight off of the arm.
6. Install the new wiper blade: Insert the new wiper blade into the wiper arm until it clicks into place.
7. Repeat steps 4-6 for the other wiper arm.
8. Test the new wiper blades: Turn on your car and test the new wiper blades to make sure they're working properly.
