The retracting electric motor is designed for mounting to the right window retractor mechanism. It ensures the electric drive of the puller’s cables or gears, thanks to which the window can be controlled with a button on the door or from the central unit in the car. When exchanging for an identical part number, the original functionality of the window controls is preserved, including comfort functions, if the car has them.

Installation recommendations:
– Before disassembly, disconnect the battery to avoid short-circuiting or unintentional switching on of the electrical circuit.
– Remove the inner lining of the right front door to gain access to the window winder and electric motor.
– Check the mechanical part of the puller (guides, cables, pulleys). If it is damaged, replace or repair it as well so that the new motor is not overstressed.
– Unscrew the original download motor and disconnect the electrical connector, then put this motor in the position of the original one and screw it firmly.
– Make sure that the gearing of the motor is properly engaged in the gear of the puller and that nothing prevents the movement of the window in the slats.
– After re-connecting the battery, test the function of the window in its entire range – smooth movement down and up, without unusual noise and stuttering.
– In some cars, basic adjustment/”learning” of the end positions of the window may be needed after the replacement by holding the button in the lower and upper positions for a longer time.

By using the original right-hand window electric motor with codes 9681577380 and 9222AS, you will get a functional replacement for the damaged part and restore the comfortable electric window control of the Citroën C4 Coupé.

This left window motor is a genuine PSA part suitable for Citroën C4 Coupé cars. This is an electric motor for the driver’s door, intended for comfortable and smooth control of the window lowering.

– Remove the door trim (upholstery) carefully so as not to damage the plastic clips and wiring.
– Check the condition of the entire puller mechanism (drives, cables, guide rails). If it is mechanically damaged, it is recommended to replace it at the same time as the engine.
– Before tightening the motor bolts, check for proper seating and alignment with the puller to avoid excessive stress or rubbing on the window.
– After assembly, reconnect the battery and test the function of the window in its full range – pull the window completely down and out several times, observe the smoothness of movement and unusual sounds.
– Some cars may require a basic initialization/”learning” of the end positions of the window after disconnecting the power – usually by holding the button in the upper and lower positions for a few seconds (depending on the specific car model and equipment).

A correctly selected and installed left window winder motor on the Citroën C4 Coupé will ensure reliable and quiet window operation, extend the life of the entire window winder and contribute to the driver’s comfort during daily use of the car.
