Description
Sunroof electric motor (sunshade) for Citroën and Peugeot vehicles. It is from Peugeot 3008 and 5008 first generation.
Description
This electric motor drives the sunshade / sunroof sliding mechanism on Citroën and Peugeot models. Designed as an OEM-fit unit for first generation Peugeot 3008 and 5008, the motor directly interfaces with the sunroof gearbox and electrical connector to open and close the interior sunshade smoothly. Ideal for professional workshops and experienced DIY mechanics who replace faulty sunroof motors or restore smooth sunshade operation.

Function And Role
The motor converts electrical input into rotary motion to drive the sunroof/sunshade cable or geartrain. It ensures precise movement, automatic stop at end positions, and integrates with the vehicle wiring harness. Proper operation is essential for comfort, protection from sun glare, and preventing mechanical jams that can damage the headliner or glass mechanism.
How Replacement Is Performed
Replacement requires moderate workshop skills and basic tools. Typical procedure:
- Park vehicle on level surface and disconnect the negative battery terminal before starting work.
- Remove interior trim and headliner access panels to reach the sunroof motor and gearbox.
- Disconnect the electrical connector and unbolt the motor from the roof frame or gearbox housing.
- Transfer any bracketry or alignment pins if applicable, and fit the new motor in the correct position.
- Reconnect electrical connector, temporarily reattach the battery and test sunshade operation through full travel to verify direction and end stops.
- Finalise torque settings on fasteners, inspect for smooth operation, then reinstall headliner panels and trim.
Installation Recommendations
- Always disconnect the battery before starting disassembly to avoid short circuits or accidental motor activation.
- Document the existing motor position and any limit or alignment settings before removal to ease correct installation.
- Check the sunroof guide rails and cables for wear, debris or corrosion while the unit is removed; addressing these prevents repeat failure.
- After installation, cycle the sunshade several times and check for unusual noise, binding or uneven movement. Adjust alignment if necessary.
- Use appropriate threadlocker or torque values for fasteners where manufacturer service guidance exists.
Common Failure Causes
- Brush and Commutator Wear: Over time carbon brushes wear down, reducing motor torque until the motor fails to move the shade.
- Mechanical Wear Or Stripped Gears: Repeated use or a jammed shade can damage the internal plastic gears or gearbox teeth.
- Water Ingress And Corrosion: Leaks in the roof area can introduce moisture that corrodes contacts or motor internals.
- Overload From Blocked Track: Dirt, foreign objects, or collapsed guide cables increase load and can burn out the motor.
- Electrical Connector Issues: Corroded or loose connectors cause intermittent operation or complete failure.
Notes For Professionals And Enthusiasts
This unit is suitable for workshops performing targeted sunroof repairs. When replacing, inspect associated components (rails, cables, limit switches) to prevent a recurrent fault. Searching by the OE numbers 12903944, 2223284 or 8401WH will help locate the correct part fast.
