Purpose and function in the wiper system

The rear wiper motor is responsible for driving the tailgate window cleaning mechanism, operating in intermittent or continuous mode according to signals from the combination switch. The component is mounted in the rear part of the body, directly connected to the wiper arm, which allows for precise reproduction of the factory operating angle and range of motion. Thanks to maintaining the original design for the Citroën brand, the motor works with the vehicle's factory electrical system, maintaining the correct operation of functions such as cyclic operation, continuous operation, and automatic wiping when reverse gear is engaged (if this function is provided in the given car configuration).

Benefits of using the original rear wiper motor

Using the original rear wiper motor in the Citroën C4 Grand Picasso allows you to maintain the consistency of the entire wiper system. Key advantages include:

• factory fit for the mountings and geometry of the tailgate,
• proper cooperation with the vehicle's electrical installation and safety systems,
• torque appropriately selected for operation with the wiper arm and blade,
• stable operation within typical load ranges and cycle frequencies. A rear wiper drive configured in this way reduces the risk of mechanism overload, incorrect arm parking, or irregular operation, which is important for both user comfort and the durability of the entire system.

Installation and operational characteristics

The motor is designed for installation in the rear of the vehicle, in the place of the factory wiper drive. The design intended for the C4 Grand Picasso allows for the use of existing mounting points and serial electrical connectors, which facilitates replacement in workshop conditions. The component comes from the used original parts group, which in practice means maintaining factory specifications while optimizing repair costs. A properly selected rear wiper motor allows you to restore full system functionality without the need for installation modifications or the adaptation of non-original solutions.

Selection by numbers and vehicle compatibility

The rear wiper motor for the Citroën C4 Grand Picasso should always be selected based on the OEM part number and available interchangeable numbers to ensure full compatibility with the specific body version and equipment. Verification by numbers allows you to avoid assembly problems, differences in mountings, or incorrect operation at the extreme positions of the arm. In case of doubt, it is useful to compare the markings from the removed component or consult the Citroën parts catalog, which minimizes the risk of selecting the wrong motor variant.
