Description
Heater servo motor for Citroën and Peugeot vehicles. You may receive a direct replacement.
Product Overview
Valeo heater servo motor (blend door actuator) T1006419G / 0902111B for Citroën and Peugeot HVAC systems. This servo controls the position of the heater/vent flap to regulate cabin temperature and airflow distribution. Commonly used as a direct replacement part, it restores proper temperature control and eliminates symptoms such as incorrect temperature, lack of airflow from selected vents, or audible clicking from the dashboard.
Key Benefits
- Direct Fit For Easy Replacement – Designed to match original mounting points and connector types for quick swap.
- Restores HVAC Functionality – Replaces worn or failed actuators to recover temperature and vent selection control.
- Suitable For Mechanics And Experienced DIYers – Clear installation steps and common fault symptoms reduce diagnostic time.
- Part Numbers For Easy Search – Customers often find this component by its product codes (see Technical Information).
Symptoms Indicating Replacement
- Clicking or grinding noises from the dash when changing temperature or vent modes.
- Unable To Select Hot Or Cold Air Properly (temperature stuck or inconsistent).
- Airflow Not Changing Between Vents (defrost/face/foot settings not responding).
- Intermittent Or No Movement From Actuator After Command.
Installation Guidance
Recommended procedure for replacement (general guide for experienced technicians or skilled DIYers):
- Disconnect The Battery Before Starting Work To Prevent Short Circuits And Protect Electronic Components.
- Access The Actuator—Usually Located Behind The Glovebox Or Under The Dashboard Near The HVAC Unit. Remove Trim Panels As Required.
- Disconnect The Electrical Connector And Remove Fixing Screws Or Clips Holding The Actuator.
- Carefully Remove The Old Actuator, Noting The Position Of Splines/Drive Shaft.
- Install The New Actuator, Aligning Splines Correctly, Fit Screws, And Reconnect The Connector.
- Before Reassembling Trim, Turn Ignition To ON And Operate HVAC Modes To Verify Proper Movement And Function.
- Reassemble Interior Panels And Reconnect The Battery.
Tip: Check Fuses And Wiring If The New Actuator Does Not Move. Do Not Force Components Into Position—verify spline alignment to avoid gear damage.
Why This Part Fails
Actuators typically fail due to mechanical wear and environmental factors rather than sudden electrical faults. Common causes include:
- Worn Or Stripped Plastic Gears From Long-Term Use Or Repeated Adjustments;
- Motor Burnout After Prolonged Cycling Or Overload;
- Ingress Of Moisture, Dust, Or Debris Causing Increased Load Or Corrosion;
- Frozen Or Obstructed Flaps Causing Excessive Strain On The Actuator;
- Age-Related Degradation—Failures Become More Frequent On Older Vehicles Or High-Mileage Cars.

Installation Recommendations
Use appropriate trim tools to avoid interior damage. Verify actuator movement before final reassembly and ensure connectors are clean and securely seated. If the actuator is not responding after installation, inspect fuses, wiring continuity, and the HVAC control module outputs. When in doubt about electronic diagnostics, use factory or professional diagnostic equipment to read actuator commands and feedback.
