Removing the Wiper Arms:
1. Disconnect the Battery: This is crucial to prevent accidental short circuits.
2. Locate the Wiper Arm Nut: The nut securing the wiper arm is usually underneath a plastic cap. Carefully pry this cap off (a small flathead screwdriver might be helpful) to expose the nut.
3. Loosen the Nut: Use a wrench of the appropriate size to loosen the nut. Don't remove it completely yet.
4. Position the Wiper Arm: With the nut loosened, carefully rotate the wiper arm to a position where it's almost vertical (pointing straight up). This helps prevent scratching the windshield.
5. Remove the Nut and Arm: Once the wiper arm is in the vertical position, completely remove the nut and carefully pull the arm straight up and off the wiper arm shaft. There might be some resistance. If it's stuck, gently rock it back and forth while pulling upwards. *Do not force it*.
6. Repeat: Repeat steps 2-5 for the other wiper arm.
Removing the Two-Piece Cowl:
This is more involved and requires patience.
1. Remove the Wiper Arms (if not already done): You'll need access to the area beneath the wiper arms.
2. Locate Cowl Clips and Screws: The cowl is held in place by several clips and possibly screws along its edges and possibly under the windshield wipers. You'll need to carefully inspect the area to locate them all.
3. Disconnect any Wiring or Vacuum Lines: There might be wiring harnesses or vacuum lines connected to the cowl. Carefully disconnect these, taking note of how they're connected for reassembly.
4. Remove the Clips and Screws: Gently pry off the plastic clips securing the cowl. Use a trim tool or a flathead screwdriver to avoid damaging the plastic. Remove any screws with a suitable screwdriver.
5. Separate the Two Pieces: The cowl usually consists of two pieces that are clipped together. Gently pry these apart, working your way along the seam.
6. Lift the Cowl: Once all the clips and screws are removed, carefully lift the cowl away from the windshield. Be mindful of any remaining connections or obstructions.
Reassembly:
Reassembly is essentially the reverse of the removal process. Make sure to securely attach all clips and screws. When reinstalling the wiper arms, ensure they are correctly aligned before tightening the nuts. Consult your repair manual for the correct torque specifications.
Important Notes:
* Repair Manual: A repair manual specific to your Windstar year is invaluable. It will provide detailed diagrams and instructions.
* Patience: This process requires patience and a careful approach. Rushing can lead to damage.
* Tools: You'll need a wrench, a flathead screwdriver (or trim removal tools), and possibly a socket set.
* Safety: Always disconnect the battery before working on electrical components.
This guide provides a general overview. Always refer to a Windstar-specific repair manual for accurate and detailed instructions. If you are not comfortable performing this repair yourself, it's best to take your Windstar to a qualified mechanic.
