Description

Mechanism for electric lowering of the left rear window for Citroën C4 Picasso and Grand cars
With electric motor
Side behind the driver

Part description

This used window winder is for the left rear window and comes with electric motor. This is a part for Citroën C4 Picasso and Grand cars, which is particularly sought after under the designation 9223C1. It is a practical solution to fix broken or stuttering windows downloads without having to hunt for individual parts separately.

The window winder mechanism is important for the smooth movement of the glass when opening and closing. If the original part stops working properly, slow operation, irregular window movement, jamming or complete non-functionality are common symptoms. Thanks to the fact that an electric motor is also part of it, replacing the unit is usually easier and faster.

Installation recommendations

Generally/typically for the power window mechanism, the exact replacement procedure may vary depending on the specific car and door design. Before the assembly itself, it is advisable to compare the used part with the old one and verify the compatibility of the attachment, connectors, shape of the mechanism and orientation for the correct side.

1) Before assembly

• Check that the mechanism is not visibly damaged, bent or dirty.
• Compare the left rear, attachment points and design of the electric motor with the old part.
• Check the condition of the wiring, connector and lead parts.
• If there is glass left in the door, secure it against spontaneous movement.

2) Necessary tools and materials

• A common set of hand tools
• Tool for disassembling interior trims
• Suitable screwdrivers and heads
• Detergent for removing dirt
• Protective gloves and possibly a flashlight

3) Step-by-step assembly procedure

1. Disconnect the vehicle’s power in the usual manner for working on electrical components.
2. Dismantle the inner door trim and carefully release access to the pull mechanism.
3. Secure the glass in a safe position so that it does not fall during disassembly.
4. Disconnect the electrical connector of the puller’s electric motor.
5. Unfasten the original mechanism and disconnect it from the glass if the design requires it.
6. Remove the old mechanism from the door without damaging the wiring or guide parts.
7. Clean the mounting area and check the condition of the attachment, glass guide and surrounding parts.
8. Put the new mechanism in place and seat it first without final tightening.
9. Attach the mechanism to the glass and check that everything fits without tension.
10. Connect the electrical connector of the electric motor.
11. Progressively fasten the mechanism at the mounting points and re-verify the correct position.
12. Before fully assembling the door, test the basic function of the window movement.
13. After verifying correct function, refit the door panel and all removed parts.
• 4) Post-assembly checks and test drive/function verification
  • Verify the smooth movement of the window in its entire range without stuttering.
  • Check that the window fits correctly and does not deviate when moving.
  • Check that the electric motor is working without unusual noises.
  • After reassembling the door, try the function several more times in a row.

  5) The most common assembly mistakes + how to avoid them

  • Swapping part side – always compare mechanism orientation before assembly.
  • Insufficient securing of the glass – there is a risk of damage to the glass or the mechanism during work.
  • Crooked mechanism seating – can cause stuttering and uneven operation.
  • Overlooking a damaged connector or wiring – even the correct part may not work.
  • Door assembly without prior testing – it is recommended to always verify functionality first.

  Reasons why the part is damaged

  • Wear of the mechanism during long-term use.
  • Increased resistance to glass movement due to dirt or clogged lines.
  • Overloading of the electric motor when the window is stuck.
  • Intrusion of moisture into the door and subsequent corrosion or deterioration of mechanical parts.
  • Damage after previous unprofessional disassembly or assembly.
  • Shock load, for example when trying to close a window against mechanical resistance.
