Product codes

Product codes: 9811039380, 1638190580, 1690042680.

The numbers are used to identify and search for the part. Their being listed with the product does not, by itself, confirm that they are interchangeable in all vehicle configurations.

Installation recommendations

The following procedure applies in general to this type of electronic part. The exact access to the unit, method of disconnecting the power supply and any required configuration depend on the specific vehicle model and equipment. Follow the manufacturer’s service procedure.

1) Before installation

First use diagnostics and inspect the electrical system to confirm that the cause of the fault is actually related to the control unit, rather than the power supply, wiring or another part of the air conditioning system.
Compare the product numbers, housing design, mounting points, number of connectors and their mechanical keying with the old unit.
Inspect the used unit: check for cracks, damaged clips, bent contacts, corrosion and signs of moisture or overheating.
If possible, record diagnostic data and the original settings before removal. Check the service documentation to determine whether replacement requires configuration or initialization.

2) Tools and materials required

Standard hand tools, depending on the actual mounting design.
Plastic trim removal tools, if covers or trim need to be released.
A diagnostic tool suitable for the specific vehicle and, if necessary, a multimeter to check the power supply according to the wiring diagram.
Lighting, a clean, dry work surface and tools for labeling connectors.

3) Step-by-step installation procedure

Park the vehicle safely, switch off the air conditioning and ignition, and secure it against unintended movement.
Follow the manufacturer’s procedure for letting the electronics go to sleep and disconnecting the battery. Do not work on the unit connectors while they are live.
Access the unit according to the service documentation. Release covers and clips without using excessive force.
Before disconnecting anything, photograph the wiring routing and connector connections, or label them if necessary.
Release the connector locks and disconnect them by pulling on the connector body, not the wires.
Release the fasteners and carefully remove the original unit without straining the surrounding wiring.
Inspect the connectors and the installation area. Address any water ingress, corrosion or damaged wires before installing the replacement part.
Compare the two units again. If the connectors or mounting differ, stop the installation; do not modify the connectors.
Position and secure the replacement unit according to the service procedure. The housing must not be subjected to mechanical stress.
Connect the connectors until their locks engage. Route the wiring so that it is not pinched, stretched or in contact with moving parts.
Restore the power supply according to the manufacturer’s instructions. If configuration or initialization is specified for this version, perform it using the appropriate diagnostic tool.
Check that the system works and, once the inspection is successful, finish installing the covers that were removed.

4) Post-installation checks and function verification

Test how the air conditioning responds to changes in settings and check the available modes according to the vehicle’s equipment.
Check the diagnostics and assess any faults; simply clearing the records does not address their cause.
Verify that the function remains stable after switching the ignition off and on again.
If it is safe to do so, monitor for a recurrence of the fault during a short test drive. The driver must not operate diagnostic equipment while driving.

5) Common installation mistakes and how to avoid them

Replacing the unit without verifying the cause: first check the power supply, wiring and related components.
Choosing a part based only on the vehicle model: also compare the unit’s markings and design, and check the requirements of the specific equipment.
Disconnecting while powered: always follow the prescribed shutdown and battery disconnection procedure.
Forcing connectors into place: check their orientation, contacts and locks; a proper connection requires no modifications.
Overlooking possible configuration requirements: check the service documentation before starting the replacement.
Failing to address moisture or an electrical system fault: fix the cause to prevent damage to the replacement unit.
