Description
Wiring harness for the left rear door (driver’s side) for Citroën Berlingo K9 and Peugeot Rifter and other Stellantis models
High-quality replacement wiring harness for the left rear door designed for Citroën and Peugeot vans and passenger variants. This cable loom (OE 9828029980) carries power and signal lines for door electronics and is a common direct-fit spare for Berlingo K9 and Rifter platforms as well as related Stellantis derivatives. Built to restore reliable operation of central locking, courtesy lighting, speakers and door sensors, this harness is aimed at professional workshops and experienced DIY mechanics who need a precise, OEM-compatible solution.

Compatibility And Fitment
Designed primarily for the left rear (driver’s side) door on Citroën Berlingo K9 and Peugeot Rifter. Also commonly used on related Stellantis platforms such as Fiat Doblo III and Toyota ProAce City where wiring layouts match. Verify connector shape and pin count visually during installation to ensure correct fitment.
Function And Typical Failures
The door wiring harness routes low-voltage power and signal lines between the vehicle body and the rear door. Typical circuits carried include central locking actuators, courtesy lamps, door ajar/position sensors, loudspeaker wiring (if fitted) and window motor wiring where applicable. The most frequent causes of failure are repeated flexing inside the rubber gaiter between body and door (broken conductors), corrosion of connector contacts from moisture ingress, damaged grommets allowing chafing, and mechanical damage after minor collisions or door impact.
How Often It Fails
There is no fixed replacement interval. Failure usually appears after many years of use and large numbers of door open/close cycles, accelerated by cracked door boots, water ingress or corrosion. Symptoms include intermittent or permanent loss of function for one or more door electronics circuits (no lock operation, speaker mute, interior light faults, or non-working window).
How To Replace
Recommended for professional technicians or experienced DIYers. Basic replacement steps:
- Disconnect the battery before starting work to avoid short circuits.
- Remove the inner door trim and any moisture shields to access connectors and the existing harness.
- Release and label connectors where necessary, detach clips and free the harness from the door.
- Carefully pull the harness through the rubber grommet/boot between door and body; replace the grommet if cracked or hardened.
- Route the new harness along the same path, secure with the original clips, reconnect all plugs ensuring correct pin engagement.
- Reconnect the battery and test all door functions (locks, lights, speakers, sensors, windows) before reassembling the door trim.
Installation Recommendations
Always follow vehicle manufacturer service procedures. Use dielectric grease on exposed connector pins to reduce future corrosion. Replace any brittle rubber boots or damaged clips during installation. Check pin alignment and wiring color codes if repair requires splicing. Tighten retained fasteners to OEM torque values and ensure no wires are trapped or excessively bent when closing the door.
Why This Part Fails Most Often
Repeated flexing of the harness inside the rubber boot is the primary cause of conductor breakage. Over time the boot can deteriorate, allowing water and dirt to enter and accelerating corrosion on connector contacts or causing chafing. Mechanical damage from accidental impacts or poor routing/clips that have fallen out can also lead to open circuits.
Notes For Professionals
Keep the OEM part code 9828029980 handy when searching stock or ordering replacements. Inspect surrounding components (grommets, clips, door hinge area) and address any root causes to prevent recurrence.
