Description
Heating servo motor for CITROEN C4 PEUGEOT 307 II
Heater servo BEHR H1959 U b 14 Citroën Peugeot EAD512 6447RZ is an electric servomotor controlling the heating and ventilation flaps in the dashboard. It ensures the correct routing and regulation of hot and cold air into the interior of the car and is thus key to the full functionality of the heating and air conditioning.
This part is suitable for selected Citroën and Peugeot models and is mainly used when replacing a malfunctioning or noisy servo motor that causes problems with temperature regulation, air flow direction or windshield defrosting.

Installation recommendations
– Before dismantling, disconnect the battery to avoid damaging the electrical installation.
– Carefully check the access to the servo motor – it is usually necessary to partially disassemble the plastic of the dashboard or the area near the heater.
– When disassembling the old part, mark the position of the flaps and connectors so that assembly takes place without incorrect rotation.
– Check the condition of the electrical connector and harness, in case of oxidation, clean and treat the contacts.
– Mount the new servomotor without violence, seat the gears correctly in the valve, tighten the screws carefully to avoid damaging the plastic mounts.
– After installation, carry out a test run – gradually switch the temperature, flow direction and air conditioning modes, whether the dampers react smoothly and without unusual sounds.
– In some cars, it may be necessary to perform a basic setting/calibration of the flaps via diagnostics – a car mechanic should know this procedure.
This servo motor is particularly suitable for car mechanics and skilled home repairers who need a reliable used part with clearly traceable codes and markings for correct assignment to a given Citroën or Peugeot model.
