Description
Overview
The Bosch heater servo motor is a direct-fit HVAC actuator designed for PSA group vehicles including Citroën and Peugeot models. Referenced by part numbers 0132801160 and 6447ER, it controls temperature and air distribution flaps to ensure reliable cabin climate management.
Function
This electronic servo motor operates the blend door or air-distribution flaps within the heater box. By moving internal flaps it regulates warm air flow and mixes hot and cold air to achieve the set cabin temperature commanded by the climate controls.
Common Symptoms And Causes
Typical failure symptoms include no temperature change, constant hot or cold airflow, audible clicking from behind the dashboard, or intermittent operation. Common causes are worn or stripped plastic gears, motor burnout, corrosion of electrical contacts, or connector and wiring faults.
Replacement And Installation
Replacement is normally performed from the passenger-side HVAC assembly. Typical steps: disconnect the battery, remove the glovebox or lower dash trims to access the heater housing, unplug the electrical connector, remove retaining screws, swap the actuator, reassemble and test. This job is suitable for an experienced DIYer or a professional mechanic with basic hand tools.
Durability And Maintenance
Servo motors are subject to mechanical and electrical wear over time; service life depends on usage and environment. Avoid forcing HVAC flaps manually and keep connectors clean and dry to reduce premature failure risks.
