Description
Product Overview
This BEHR heating servo motor is a direct-fit HVAC actuator designed for Citroën and Peugeot passenger cars. Supplied as part number EAD515 / P2861001U (b 44 / 647947), it controls air distribution and temperature flaps in the heater and ventilation box to ensure accurate cabin climate control. The unit is intended for use on Citroën C5 X7 and Peugeot 407 Facelift models and is frequently searched by its part numbers for quick identification.
Key Benefits
- Direct replacement for OE actuators with matching electrical connector and mounting points.
- Restores precise control of blend and distribution flaps for consistent heating and ventilation performance.
- Ideal for professional mechanics and experienced DIY technicians performing HVAC repairs.
- Part numbers included for fast cross-referencing and compatibility checks.
Function And Symptoms Of Failure
The servo motor drives the HVAC blend or distribution flaps inside the heater box, translating electrical control signals from the climate control unit into precise flap movement. Common symptoms of a failing actuator include intermittent or stuck flaps, incorrect cabin temperature, rattling or clicking noises from behind the dashboard, and error codes related to HVAC position feedback.
Typical Causes And Lifespan
Failures are usually caused by worn plastic gears, motor wear, internal potentiometer or sensor faults, or connector corrosion from moisture and age. Lifespan depends on vehicle use and environment; many actuators last a decade or longer, but heat cycling and mechanical wear eventually require replacement.
Replacement And Installation Notes
Replacement is a moderate-difficulty job. Access is typically through the glovebox area or under the dash on the passenger side depending on the model. General steps:
- Disconnect the vehicle battery before starting to avoid electrical shorts.
- Remove glovebox or trim panels to reach the heater box access point.
- Unplug the electrical connector from the old servo motor and remove mounting screws.
- Install the new actuator, secure mounting screws, and reconnect the electrical plug.
- Reconnect the battery and cycle the climate control through its positions to confirm correct operation and flap movement.
For safety, follow manufacturer service instructions and take care with fragile dash trim. The job is suitable for professional workshops and competent DIYers with basic hand tools.
Troubleshooting Tips
- If you hear clicking but flaps do not move, inspect for stripped gears or broken linkage inside the heater box.
- Check connector pins for corrosion and wiring continuity if the actuator receives no power.
- After replacement, verify full range of motion by commanding different climate settings and listening for smooth operation.
