Description
Heater servo motor for Citroën and Peugeot vehicles. You may receive a direct replacement.
Description
High-quality heater servo motor (heater actuator) designed for Citroën and Peugeot HVAC systems. This servo controls flap position inside the heating and ventilation box to regulate air distribution and temperature blending. Ideal for workshops and DIY mechanics who need a reliable replacement part referenced by product codes T1006419G and 0902111B. Compatible with vehicles in which the original part numbers match these codes.
Technical Information

- Product Codes: T1006419G, 0902111B
- Other Numbers: Stellantis references may appear on packaging or listings
Function and Benefits
The heater servo motor moves HVAC flaps to control airflow direction and to mix hot and cold air for cabin temperature regulation. A correctly functioning servo ensures precise climate control, reduces cabin discomfort and prevents inconsistent ventilation. Replacing a faulty servo restores proper blower routing and prevents unwanted noise.
Typical Symptoms Of Failure
- Incorrect air distribution (air blows from wrong vents)
- Inability to change temperature (stuck hot or cold)
- Clicking or grinding noises from the dashboard area
- Intermittent or no response from climate control settings
Why The Part Commonly Fails
Failures are usually mechanical or electrical: plastic gear teeth wear or strip, internal motor brushes degrade, potentiometer or position sensor faults occur, and contamination or moisture can cause corrosion or seizure. Mechanical obstruction in the HVAC box (debris) and long-term thermal cycling also accelerate wear.
Replacement Procedure
General replacement steps for experienced mechanics and competent DIYers:
- Disconnect the negative battery terminal before starting work to avoid short circuits when handling electrical connectors.
- Gain access to the HVAC unit—most applications require removal of the glovebox or lower dashboard trim on the passenger side.
- Locate the defective servo on the heater box; remove any retaining screws or clips and unplug the electrical connector.
- Compare the new unit with the removed part (verify product codes: T1006419G / 0902111B).
- Install the replacement servo, secure mounting screws, reconnect the electrical connector and reassemble all trim panels.
- Reconnect the battery and verify full operation of the climate control system, cycling through all vent positions and temperature settings.
Installation Recommendations
- Perform installation in a clean, dry workspace to avoid introducing debris into the HVAC box.
- Handle electrical connectors carefully—do not force pins—and ensure connectors are fully seated.
- Check surrounding ductwork and flaps for broken pieces or foreign objects before fitting the new servo.
- After installation, confirm there are no unusual noises and that all flap positions respond correctly across the control range.
Notes For Buyers
If the original part number on your unit matches T1006419G or 0902111B, this servo is a suitable replacement. Always verify the product codes listed in the Technical Information section against the part being replaced. This listing is intended for mechanics and competent DIYers familiar with dashboard disassembly and HVAC systems.
