Description
Overview
This BEHR heater servo motor restores precise control of the heating and ventilation system in PSA vehicles. Supplied with OE cross-references EAD516, P1975001 and 647948, it replaces worn or failed HVAC actuators commonly found on Citroën C5 (X7) and compatible PSA models. The unit is intended to bring back accurate blend-door movement and consistent cabin temperature control.
Key Benefits
- Direct-fit replacement for referenced OE numbers for quick service
- Restores accurate blend-door operation and consistent temperature control
- Robust motor and gearbox assembly designed for prolonged service life
- Suitable for professional workshops and experienced DIY mechanics
Compatibility
Typically fitted to Citroën C5 (X7). The part is used across PSA group vehicles where OE references EAD516, P1975001 or 647948 apply. Always verify fitment with vehicle VIN or OE cross-reference before ordering to ensure correct application.
Common Faults And Causes
- Clicking or grinding noises from the dash caused by worn plastic gears or stripped teeth
- Loss of precise temperature control or only extreme hot/cold output due to motor failure or internal gear slip
- Intermittent operation from corroded electrical connectors or wiring faults
- Stiff or stuck blend door causing overload and premature actuator failure
Replacement & Installation
- Disconnect the negative battery terminal before starting any electrical work.
- Gain access to the HVAC housing; glove box or lower dash removal is commonly required to reach the actuator.
- Unplug the electrical connector and remove the fixing screws securing the actuator to the housing.
- Install the new actuator, tighten fasteners to the correct torque, reconnect the electrical plug and restore battery connection.
- Cycle the climate control through its full range to allow the actuator to self-position; confirm correct operation and absence of unusual noises.
When To Replace
Replace this servo motor if you experience persistent clicking, loss of temperature control, or diagnostic trouble codes pointing to an actuator fault. Lifespan depends on usage and environmental exposure; common causes of failure include gear wear, electrical corrosion and contamination ingress.
