Function
The switch provides the electrical command to the rear window motor, completing circuits for raising and lowering the glass. It contains sliding or contact-type electrical contacts and a mechanical actuator that sends the driver’s input to the window regulator motor. Proper operation ensures smooth, controlled window travel and integration with central locking or child-lock circuits where applicable.
Installation Recommendation
Recommended for qualified mechanics and experienced DIYers. Typical replacement steps:
- Disconnect the negative battery terminal to avoid shorts and accidental motor operation.
- Remove the door trim using appropriate trim tools to avoid damaging clips and upholstery.
- Unscrew or unclip the old switch module and unplug the electrical connector.
- Compare the new switch to the removed unit (pin layout and housing) and connect the wiring harness.
- Test the switch operation before reassembling the door panel—verify up/down travel and any lock-out functions.
- Reinstall trim and secure all fasteners, then reconnect the battery and perform a final test.
Tip: Inspect the connector for corrosion or bent pins and clean contacts with electrical cleaner if necessary. If the window motor is sluggish after replacement, check the regulator mechanism and track lubrication.
Why This Part Fails Most Often
- Wear Of Electrical Contacts: Repeated use causes contact pitting and increased resistance, leading to intermittent operation.
- Moisture Ingress: Water or humidity entering the switch or connector can corrode contacts and cause shorting.
- Mechanical Breakage: Plastic buttons or mounting tabs can crack from force or aging, preventing proper actuation.
- Wiring Or Connector Faults: Damaged harnesses, bent pins, or poor grounding can mimic switch failure.
Fitment And Search Tips
When searching, include the part number 6552ZG and vehicle model (Peugeot 406, Citroën C3, Citroën C3 Pluriel) to quickly find compatible units. Verify physical appearance and connector layout against the original switch to ensure correct fitment.
If you service multiple vehicles, keep spare switches and basic trim tools on hand to minimize workshop downtime—replacing a faulty rear window switch is a fast repair that typically restores full window function and customer satisfaction.
