Symptoms and warning signs

Recognizing the early symptoms can help you address the issue before it becomes a major safety concern. If your 1998 Ford Explorer is experiencing a windshield wiper motor intermittent operation, you might notice:

• Wipers stop working suddenly: The most common symptom, where the wipers simply cease movement without warning.
• Inconsistent operation: Wipers work for a period, then stop, then resume again on their own.
• Wipers only work on one speed: Even if you select different speed settings, the wipers operate at a single, often slow, speed.
• Wipers get stuck mid-sweep: The blades may stop in the middle of the windshield rather than returning to their park position.
• Wipers operate slowly or weakly: The motor seems to struggle, moving the wipers at a reduced pace.
• Delay in response: There's a noticeable lag between activating the wipers and them actually starting to move.
• Wipers don't park correctly: The blades might stop above or below the designated park position.

How to verify and confirm the issue

To confirm that your 1998 Ford Explorer's intermittent wiper operation is indeed related to the motor or its associated components, you can perform several checks:

• Check fuses: Locate the fuse box (typically under the hood and/or inside the cabin) and inspect the fuse for the windshield wipers. A blown fuse will have a broken filament. Replace any blown fuses with one of the correct amperage.
• Listen for the motor: When you turn on the wipers, listen closely for any sound from the wiper motor, usually located under the cowl panel at the base of the windshield. If you hear a humming or clicking but no wiper movement, the motor might be trying to work but is mechanically bound or failing.
• Visual inspection of linkage: With the hood open, inspect the wiper linkage arms and bushings for any signs of corrosion, looseness, or damage. A seized linkage can put excessive strain on the motor, leading to intermittent operation or failure.
• Test the multi-function switch: The multi-function switch (also known as the turn signal or stalk switch) controls the wipers. If other functions on the switch (like turn signals or high beams) are also acting up, it points to a faulty switch. You can test continuity with a multimeter if you have the wiring diagram.
• Direct motor test (advanced): If comfortable with basic electrical work, you can disconnect the wiper motor's electrical connector and apply 12V directly to the motor's power and ground terminals (consult a wiring diagram for the correct pins). If the motor runs consistently when direct power is applied, the issue is likely upstream (switch, relay, wiring). If it still runs intermittently, the motor itself is faulty.

Common causes (most likely first)

The intermittent operation of your 1998 Ford Explorer's windshield wipers can stem from several issues, ranging from simple electrical problems to component failure:

• Faulty wiper motor: Over time, the internal components of the wiper motor (brushes, armature, gears) wear out, leading to inconsistent power delivery or mechanical binding.
• Bad multi-function switch: The stalk-mounted switch on the steering column controls wiper speeds and functions. Worn contacts inside the switch can cause intermittent electrical connection.
• Corroded or loose wiring/ground: Poor electrical connections, especially a corroded ground wire for the wiper motor, can cause intermittent power supply.
• Blown fuse or faulty relay: A fuse protects the circuit from overcurrent, while a relay switches power to the motor. Either can fail, causing intermittent or complete loss of function.
• Seized wiper linkage: While less common for intermittent operation and more for complete failure, stiff or seized linkage arms can put excessive load on the motor, causing it to overheat and temporarily shut down.

Step-by-step diagnosis and fixes

Diagnosing and fixing your 1998 Ford Explorer's intermittent wiper issue systematically can save time and effort:

• Step 1: Check the fuse: Always start with the simplest solution. Locate and inspect the wiper fuse. Replace if blown.
• Step 2: Inspect the relay: Many vehicles use a relay for the wiper motor. You can try swapping the wiper relay with another identical relay from a non-critical system (like the horn, if it's the same type) to see if the problem resolves. If it does, replace the relay.
• Step 3: Test the multi-function switch: With a multimeter, test the continuity of the multi-function switch according to your vehicle's service manual. Look for inconsistent readings or open circuits when the switch is in different positions. Replacement of the switch is a common repair.
• Step 4: Inspect wiring and ground: Visually check the wiring harness leading to the wiper motor for any signs of fraying, corrosion, or damage. Pay close attention to the ground wire connection, often bolted to the chassis. Clean any corrosion and ensure a tight connection.
• Step 5: Test the wiper motor: If the above steps don't resolve the issue, the motor itself is likely at fault. As mentioned in the verification section, you can test it directly with 12V power. If it fails the direct test, replacement is necessary.
• Step 6: Check wiper linkage: Ensure the wiper arms move freely. Lubricate pivots if they are stiff. If any components are bent or broken, they will need replacement. You can find more specific repair guides for your vehicle by exploring All repair guides.
