Solution

1. Preparation

Gather necessary tools and parts.
Disconnect the vehicle battery to prevent electrical shock.
Ensure the vehicle is parked on a flat surface with the engine off.

2. Inspect and Replace the Wiper Fuse

Tools Required: Fuse puller or needle-nose pliers.
Locate the fuse box (usually under the dashboard or in the engine compartment).
Identify the wiper fuse (refer to the diagram on the fuse box cover).
Pull the fuse out and inspect it for continuity.
If the fuse is blown, replace it with a new fuse of the same amperage.

3. Test and Replace the Wiper Motor

Tools Required: Multimeter, jumper wires.
Reconnect the battery and activate the wiper switch.
Use a multimeter to measure voltage at the wiper motor connector.
If voltage is present but the motor does not operate, remove the wiper motor.
Replace the motor with a new or tested good unit.
Reconnect all electrical connections and ensure they are secure.

4. Inspect and Replace the Wiper Control Switch

Tools Required: Screwdrivers, multimeter.
Remove the steering column covers to access the wiper control switch.
Use a multimeter to test the switch for continuity in all positions.
If the switch fails the continuity test, replace it with a new unit.
Reassemble the steering column covers.

5. Inspect the Wiper Linkage

Tools Required: Socket set, grease.
Remove the wiper arms by loosening the retaining nuts and gently pulling them off.
Inspect the wiper linkage for any signs of damage or binding.
If the linkage is damaged, replace it.
Apply grease to any moving parts to ensure smooth operation.
