- Impact from ice or debris
- Excessive strain due to stiff wiper blades or motor defects
- How to Address Its Problems
- Regularly lubricate the moving parts to reduce friction and wear
- Inspect the transmission periodically for any visible damages or misalignments
- If the transmission appears bent or broken, consider replacing it with a new one
Control Switch Malfunctions
The control switch is the user’s direct interface with the wiper system. Over time, it can suffer from a variety of issues due to electrical or mechanical failures.
- Deep Dive into Control Switches
- Typically located on the steering column or dashboard
- Offers multiple settings, including wiper speed and mode of operation
- Relies on internal circuits and contacts to relay user commands to the wiper system
- Why Switches Fail
- Moisture infiltration leading to short circuits
- Wear and tear of internal components from regular use
- Electrical issues elsewhere in the system causing the switch to malfunction
- Repair and Replacement Tips
- Always turn off the vehicle before working on electrical components
- Use a multimeter to test the switch for continuity
- If signs of damage or wear are evident, replace the control switch with a compatible model for the Ford Escape
Faulty Relay
Relays are essential components in many of a vehicle’s electrical systems. For the windshield wipers, the relay acts as a bridge between the control switch and the wiper motor, ensuring power flow and correct operation.
- Function and Importance of Relays
- They control high-current circuits using a smaller current
- Ensure that the wiper motor receives power when activated
- Help in protecting sensitive components from potential electrical surges
- Typical Symptoms of a Failing Relay
- Inconsistent wiper operation or complete failure
- Other electrical components malfunctioning
- Unusual sounds, like buzzing or clicking, when attempting to use the wipers
- Diagnosing and Resolving Relay Concerns
- Relays are often located in the main fuse box
- Use a relay tester or multimeter to check for any faults
- Replace with a specified relay for the Ford Escape, ensuring it matches the requirements
Advanced Diagnostics
Multimeter Testing
Utilizing a multimeter can be a game-changer when trying to pinpoint electrical issues within the wiper system. This device measures multiple electrical properties, such as voltage, current, and resistance.
- Setting Up and Safety Tips
- Always disconnect the vehicle battery before working on electrical components
- Familiarize yourself with the multimeter’s functions and settings
- Use gloves and ensure you’re working in a dry environment
- Procedure for Testing the Wiper Motor
- Attach the multimeter’s probes to the motor’s terminals
- Set the device to measure resistance
- A reading that significantly deviates from the norm indicates a potential issue
Checking Wiper Linkage
The linkage plays a pivotal role, ensuring that the movement of the wiper blades is synchronized and effective.
- Key Components of Wiper Linkage

- Pivot points
- Bushings and joints
- Common Problems and Their Causes
- Linkage popping out due to worn bushings
- Corrosion leading to stiff movement or breakage
- Misalignment causing wipers to collide or not cover the full windshield area
- Inspecting and Addressing Linkage Issues
- Visually inspect the linkage for any signs of damage or wear
- Manually move the wipers to feel for any unusual resistance or movement
- Replace or repair any damaged components to restore full functionality
Sensor Failures
Modern Ford Escapes often come equipped with rain sensors for automatic wiper activation. However, these sensors are not immune to malfunctions.
