Air conditioning control with Citroën Peugeot 55900-040

Description

Heating control and manual air conditioning for CITROEN C1 and PEUGEOT 107 cars up to 2014
With control rods

Part description

The used Citroën C1 / Peugeot 107 heating and manual air conditioning control is intended for adjusting the heating and air conditioning in the cabin. It is a suitable choice when replacing a damaged control panel, for example if its controls are mechanically worn or damaged. The designation 55900-0H040 is especially important for finding the part.

The components are control rods which transmit the movement of the controls to the respective mechanisms. Before replacing, it is advisable to distinguish between a defect in the panel itself and a stiff tie rod or connecting mechanism – their excessive resistance can damage even the replacement controller.

When choosing, compare the designation of the original part, the design of the panel, the attachment, the connection and the end of the rods. The figures given are from the product documentation; they do not in themselves confirm the mutual interchangeability of all designs.

Installation recommendations

In general, the following procedure applies to this type of part. The exact method of accessing the panel, disconnecting the tie rods and any adjustment depends on the specific model and design of the car. Follow the manufacturer’s service procedure.

1) Before assembly

• Compare the part numbers, driver layout, mounting points and any electrical connectors with the old piece.
• Check the number, length, routing and termination of the tie rods, including the attachment of their covers.
• Inspect the plastic brackets, latches and controls. Look for cracks, deformations or loose parts.
• Finely check the operation of the controls and pull rods. Do not force the resistance and do not turn the controls beyond the stops.
• Check the free movement of the subsequent mechanisms so that the cause of the original defect does not damage the replacement panel.

2) Necessary tools and materials

Usually, suitable screwdrivers or bits depending on the connections used, plastic disassembly levers for the lining, a flashlight and tools to mark the connections are sufficient. Also prepare a container for fasteners and a phone to record the original routing of the tie rods. Adapt the exact selection of tools to the design of the car.

3) Step-by-step assembly procedure

1. Secure the vehicle against movement, turn off the ignition and disconnect the battery according to the manufacturer’s procedure before disconnecting the electrical connections.
2. Carefully loosen the necessary covers and trim according to the service procedure. Do not apply excessive force to the plastic latches.
3. Photograph the position of the original panel, the routing of the rods, their fastening and any electrical connections.
4. Unfasten the panel and pull it out just enough to avoid straining the tie rods or wiring.
5. Mark individual connections. Disconnect any electrical connectors after releasing the fuses, not by pulling on the wires.
6. Release the clamps and tie rod ends in the order prescribed by the manufacturer. Record the position of the controls and follow-up mechanisms.
7. Remove the original part and compare it again with the replacement panel including the tie rods and attachment points.
8. Store the rods in the corresponding guide without sharp bends and pinches. Place their covers and ends in the correct holders; make any settings according to the service procedure.
9. Connect the electrical connectors if they are part of the design. Check their securing and free cabling.
10. Prior to final fixing, gently test the mechanical operation of the controls in their full range. If there is unusual resistance, stop the movement and check the guide and attachment of the rods.
11. Attach the panel, replace the covers and trim, and connect the battery according to the manufacturer’s instructions. Then perform a function check.

• 4) Post-assembly checks and function verification

  • Verify smooth operation of controllers without jamming and self-returning.
  • Try changing temperature settings, air distribution and other functions according to the actual design of the panel.
  • Assess the function of the heating and air conditioning under the conditions that allow their operation. Insufficient heating or cooling may not be caused by the controller.
  • Check the tight fit of the panel and trim. Do a possible short test drive only after complete assembly and verification of basic functions on site.

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

  • Replacing tie rods: mark and document their original wiring prior to disassembly.
  • Insufficiently secured tie rod cover: verify that all clips are seated, otherwise the movement of the controller may not be transmitted properly.
  • Pinch or sharp bend in tie rod: follow the original routing and check it before fitting the covers.
  • Misalignment of actuator and mechanism positions: follow the manufacturer’s adjustment procedure to allow the actuator to reach its full working range.
  • Overcoming resistance by force: first remove the cause of stiffness; forceful rotation can damage plastic parts and tie rods.

  Reasons why the part is damaged

  For heating controls and manual air conditioning with push rods, the general causes of damage are especially:

  • Wear of control mechanisms during long-term use.
  • Aging of plastics and their stress due to temperature changes in the interior.
  • Increased resistance of links or follow-up mechanisms which overloads controls and handles.
  • Force control through stops or when the mechanism is stuck.
  • Reckless disassembly or incorrect assembly, for example broken clips or incorrect routing of the tie rods.
  • Intrusion of dirt or liquids which can impair mechanical operation and damage possible electrical contacts.
