Description
BEHR Control Module For Heating And Air Conditioning Fan For PEUGEOT 3008 And 5008 First Generation
This BEHR control module regulates the blower motor for the heating and air conditioning system on first‑generation Peugeot 3008 and 5008 models. Designed as a direct replacement for the original climate‑control electronics, the unit restores proper blower speed control, enables smooth ramping between fan stages and integrates with the vehicle’s HVAC controls. Ideal for professional workshops and competent DIY technicians, this part is often searched for by its product numbers P7708004, P7708003 or 6441CQ.
Features And Benefits
Reliable blower regulation from a well‑known supplier: precise fan speed control reduces cabin noise and improves climate comfort. Direct fitment for the original wiring and mounting points makes installation straightforward for trained mechanics. Replacing a faulty module typically returns full functionality without the need to replace the blower motor, provided the motor and wiring are in good condition.

Symptoms Indicating A Faulty Module
- Blower works only at one speed (usually high) or only at low speed.
- Intermittent fan operation or no fan at all despite the HVAC controls appearing functional.
- Unusual buzzing or loss of smooth fan speed transitions.
- Electrical smell or visible heat damage at the connector or module.
Common Causes Of Failure
The most frequent reasons for control module failure are thermal stress from high current demand, water or moisture ingress into connectors, corrosion of electrical contacts, and damage caused by a failing blower motor that draws excessive current. Short circuits in the blower wiring or repeated overheating during heavy use accelerate degradation of electronic components.
Replacement And Installation Recommendations
Follow these practical steps and recommendations to ensure a safe and durable replacement:
- Disconnect the vehicle battery before any work to avoid short circuits and protect the electronics.
- Access the module—on these models the blower control module is typically mounted on or near the HVAC housing behind the glovebox or lower dash. Remove the glovebox or lower trim as required to reach the unit.
- Unplug the electrical connector and remove the fasteners securing the module. Fit the new module in the same orientation and secure it with the original fasteners.
- Inspect the blower motor and wiring before final assembly: measure motor current and check for worn brushes or seized bearings. If the motor draws excessive current, it can quickly damage a new control module.
- Apply dielectric grease to connectors to reduce the risk of corrosion and ensure firm pin engagement.
- After installation, reconnect the battery and test all fan speeds and HVAC modes. Verify there are no error messages and that airflow changes smoothly across settings.
Why Replacing The Module Alone May Not Be Enough
If the underlying cause is a failing blower motor, degraded wiring or a shorted connector, simply fitting a new control module can result in repeated failures. Always check the blower motor, fuse, and wiring harness for excessive current draw, heat damage or corrosion before installing the replacement module.
Notes For Professionals
This control module is a direct replacement part compatible with the listed Peugeot models and the referenced product codes. It is suitable for fitment by professional car electricians and experienced DIY mechanics familiar with vehicle HVAC systems and basic electrical diagnostics.
