how do I fix my Ford Mustang S650 (2024-Present) wipers not working?

Solution

1. Preparation

• Tools Required: Screwdriver set, multimeter, wire brush, safety goggles, gloves.
• Ensure the vehicle is parked on a level surface and the engine is off.

2. Check the Wiper Fuse

• Locate the Fuse Box: Find the fuse box under the dashboard or in the engine compartment.
• Remove Fuse: Use a fuse puller or needle-nose pliers to remove the wiper fuse.
• Inspect the Fuse: Look for a blown fuse (broken filament). Replace with a fuse of the same amperage if damaged.

3. Test the Wiper Switch

• Disconnect Battery: Disconnect the negative terminal of the battery for safety.
• Access the Wiper Switch: Remove the steering column cover if necessary.
• Perform Continuity Test: Use a multimeter to check for continuity through the switch in all positions (off, low, high, and intermittent).
• Replace Switch if Faulty: If the switch is defective, disconnect and replace it with a new one.

4. Inspect Wiring and Connectors

• Visual Inspection: Check for frayed wires or loose connectors in the wiper circuit.
• Clean Connections: Use a wire brush to clean any corroded connections. Secure all connections properly.

5. Test the Wiper Motor

• Direct Power Test: With the battery still disconnected, connect the wiper motor directly to the battery using jumper wires.
• Observe Motor Operation: If the motor runs, it is functioning properly. If not, replace the wiper motor.

6. Reassemble and Test

• Reconnect Battery: Reconnect the negative terminal of the battery.
• Reassemble Components: Replace any covers removed and ensure all components are secured.
• Test Wipers: Turn on the wiper switch to confirm proper operation.
