Description
BEHR control module for the heating and air conditioning blower for PEUGEOT 3008 and 5008 first generation. Supplied with a length of wiring.
Overview
This BEHR blower control module is a direct-fit solution for the heating and air conditioning fan on PEUGEOT 3008 I and 5008 I. Designed for professional workshops and experienced DIY mechanics, the unit controls blower speed and ensures reliable airflow for cabin heating and climate control. Commonly sought under part numbers such as P7708004, P7708003 and 6441CQ, this module is supplied with a short wiring lead to simplify replacement and electrical connection.
Why Choose This Part
Replacing a faulty blower control module restores precise fan speed regulation, reduces noise and prevents uncontrolled fan behavior. Using a correct OE-equivalent component from a reputable supplier like BEHR helps maintain climate system performance and passenger comfort.
Fitment And Typical Applications
Intended for PEUGEOT 3008 I and PEUGEOT 5008 I models where the original blower control module uses the listed reference numbers. Ideal for mechanics and technicians who search by product code (P7708004, P7708003, 6441CQ) when sourcing replacement parts.
Replacement Procedure
- Safety First: Disconnect the negative battery terminal before any work on the HVAC electrical system.
- Access: Remove the glovebox or lower passenger-side trim to access the blower motor housing. The control module is usually mounted on or near the blower motor assembly inside the HVAC plenum.
- Disconnect: Unplug the electrical connector and carefully detach the wiring harness supplied with the unit if applicable.
- Remove: Unscrew the module mounting screws or clips and extract the old unit from the blower housing.
- Install: Fit the new control module, secure with screws, connect the wiring harness and plug in the connector. Ensure routing avoids sharp edges and heat sources.
- Test: Reconnect the battery, start the vehicle and verify all fan speeds and climate functions operate correctly.
Recommended For Installation
Installation should be performed by a trained technician or an experienced DIY mechanic with basic electrical knowledge. Always disconnect the battery before starting and follow manufacturer procedures for disassembly and reassembly to avoid damage to trim and HVAC components. Check for signs of water ingress at the evaporator drain and inspect the blower motor for excessive wear before fitting the new module—an overloaded motor can shorten the life of a new control unit.
Common Failure Causes
Blower control modules typically fail due to prolonged heat exposure, corrosion from moisture ingress, electrical overload caused by a failing blower motor, or accumulated debris restricting fan movement. Symptoms include loss of fan speeds, fan stuck at one speed, intermittent operation or burning smell from the HVAC area.

Notes For Mechanics
When fitting this module, verify connector type and mounting orientation to ensure a secure electrical and mechanical connection. If the original unit failed due to motor overload or water ingress, address the root cause (replace or service blower motor, clear evaporator drain) to avoid repeated failures.
