Description
BEHR Heater Servo Motor For Peugeot 3008 And 5008 First Generation. The Gear Section Can Be Removed And The Motor Can Be Used On Its Own.
Reliable replacement BEHR heater servo motor designed for climate control systems in the first‑generation Peugeot 3008 and 5008. This compact electric actuator drives HVAC flaps to regulate cabin temperature and air distribution. The removable gear section offers flexibility: workshops can reuse only the motor if the plastic gear set is worn, reducing repair costs and downtime. Ideal for professional mechanics and experienced DIY enthusiasts who search by part number (EAD516 / P1975001 / 43647998) when ordering spare parts.
Technical Information
Manufacturer: BEHR
Model: Peugeot 3008 I, Peugeot 5008 I
Product Codes: EAD516, P1975001, U
Additional Numbers: 43 647998 (43647998)
Function
The servo motor operates the heater/blend door or air flap inside the HVAC unit to mix hot and cold air and direct airflow to the windshield, face or feet vents. It receives position commands from the climate control module and converts electrical input into precise rotary motion to position internal flaps.
Common Failure Causes
- Worn Or Stripped Plastic Gears: Repeated use and age cause the small plastic gear teeth to wear or break, preventing correct flap movement.
- Motor Bearing Wear Or Electrical Faults: Bearings may seize or the motor windings/connectors can fail due to heat and humidity over time.
- Connector Corrosion Or Poor Contact: Moisture ingress or oxidized terminals cause intermittent operation or complete loss of function.
- Mechanical Obstruction In HVAC Box: Debris or broken duct parts can jam the actuator and accelerate gear damage.
Replacement And Installation
Replacement is straightforward for workshops familiar with Peugeot HVAC layouts. Typical steps:
- Remove Lower Dash Panels Or Glovebox To Access HVAC Housing Depending On Model.
- Locate The Faulty Servo Motor On The Heater Box, Unplug The Electrical Connector And Release Fasteners.
- Remove The Actuator From The Flap Shaft; If Replacing Only The Motor, Detach The Gear Section As Needed.
- Fit The New Unit, Ensure Proper Engagement With The Flap Shaft, Reconnect The Electrical Connector And Reassemble Interior Trim.
Always Disconnect The Battery Before Starting Work To Avoid Short Circuits And To Prevent Damage To The Vehicle Electronics. After Installation, Verify Correct Flap Movement And HVAC Functions Through All Modes.
Installation Recommendation
For Best Results, Install By A Qualified Mechanic Or An Experienced DIYer With Basic Automotive Tools. Inspect The HVAC Box For Debris And Check The Mating Flap Shaft For Play Or Damage Before Fitting The New Actuator. If Gear Damage Is Present, Consider Replacing The Gear Section Or The Entire Actuator To Ensure Long‑Term Reliability.
Why The Part Most Often Fails
Plastic Gear Wear Is The Predominant Cause. The Small Plastic Teeth Are Under Constant Load And Are Vulnerable To Fatigue, Especially When HVAC Flaps Are Resisted Or Jammed. Heat And Humidity In The Dash Area Accelerate Material Degradation, While Electrical Connector Issues Can Cause Intermittent Faults That May Be Misdiagnosed.
