Purpose and Function of the Rain Sensor

The front windscreen rain sensor in Ford B-Max and Fiesta Mk7 models works with the wiper system, analyzing the amount of water on the glass and sending a signal to the controller. This allows the wipers to operate in automatic mode, adjusting their frequency to the current road conditions.

The location on the vehicle specified as front means it is mounted in the area of the front windscreen, within the direct operating range of the wipers. A properly functioning sensor contributes to:

• stable and predictable wiper operation in AUTO mode,
• improved visibility during sudden rain showers or drizzle,
• increased driving safety in urban and long-distance traffic.

Characteristics as an Electronic Control Module

The presented item belongs to the group of Electronic Control Modules and Controllers, meaning it interfaces with the vehicle's electrical system and body control module. The sensor generates an input signal for the controller responsible for wiper operation, and depending on the vehicle's configuration, it may also interact with other comfort functions.

As part of the Ford brand, the module is designed for compatibility with the vehicle's factory electrical architecture. Proper fitment to the windscreen and mounting bracket is crucial for accurate weather condition readings and stable long-term operation.

Condition, Origin, and Service Application

The offered rain sensor is a used item, which in service practice often represents a sensible compromise between repair cost and maintaining the original manufacturer's specifications. Such components are frequently used for:

• damage to the factory sensor after a collision or windscreen replacement,
• diagnosing wiper system faults related to automatic mode,
• restoring full functionality of comfort features in Ford B-Max and Fiesta Mk7.

Due to the nature of an electronic module, it is recommended to verify compatibility with the specific vehicle equipment version and system configuration before installation.

Selection by OEM Number and Compatibility

For rain sensors, selection by OEM number and interchangeable numbers is crucial to ensure proper cooperation with the electrical system and body controller. Correct matching minimizes the risk of wiper operation errors, fault messages, and problems with automatic mode activation.
