Description
BEHR heater servo motor for PEUGEOT 3008 and 5008 first generation. The toothed gear section can be removed and the motor used alone.
Overview
High-quality BEHR heater servo motor designed for climate control systems in first-generation Peugeot 3008 and 5008. This electric actuator operates HVAC flaps to regulate airflow direction and temperature within the passenger compartment. It is a popular replacement part for workshops and DIY mechanics searching by OE and aftermarket codes such as EAD516, P1975001 or 647998.
Technical Information

Function And Benefits
The servo motor drives the HVAC blend/door mechanism to direct airflow and mix hot and cold air for accurate cabin temperature control. Replacing a worn or failed actuator restores proper vent selection, eliminates clicking or grinding noises from the dashboard, and brings back reliable automatic climate control behavior.
Replacement Procedure
Typical replacement can be performed in a workshop or by an experienced DIY mechanic with basic tools. General steps:
- Gain access to the actuator (often behind the glovebox or center console depending on vehicle configuration).
- Disconnect the electrical connector and remove mounting screws.
- Remove the old actuator; if required, separate the toothed gear from the housing (this product allows the gear to be removed and the motor to be used alone).
- Fit the replacement unit, reconnect the connector and fasten screws to the manufacturer’s torque recommendations.
- Verify correct operation by cycling the climate control through all modes and temperatures before reassembling interior trim.
Installation Recommendations
- Disconnect the battery before starting work to avoid short circuits and prevent damage to vehicle electronics.
- Handle plastic gears and levers gently; avoid forcing linkages to prevent secondary damage.
- Test actuator movement with the HVAC controls before final reassembly to ensure proper calibration and full range of motion.
- Use correct fasteners and do not overtighten screws to prevent cracking the housing.
Common Failure Causes
Actuators typically fail due to gear wear or stripped teeth, water ingress and corrosion, seized bearings in the motor, or intermittent electrical faults at the connector. Symptoms include audible clicking or grinding from the dash, incorrect vent selection, inability to change cabin temperature, or a permanently stuck flap. Failures are more common after several years of use or exposure to moisture and dust.
Why Choose This Unit
This BEHR actuator is a practical solution when the motor remains serviceable but the plastic gear is damaged — the removable gear section gives flexibility for repairs and can reduce replacement cost. Ideal for professional garages and competent DIYers who need a direct-fit part identified by OE numbers P1975001 / 647998 / EAD516.
Note
Always follow the vehicle manufacturer’s service instructions during removal and installation to avoid damage. After installation, confirm proper HVAC operation across all settings.
