Replacement Procedure
Typical replacement steps for a competent mechanic or experienced DIYer:
- Disconnect the vehicle battery before any work to avoid short circuits and possible damage to the module or vehicle electronics.
- Access the blower motor housing—on many PSA vehicles the control module is mounted on or near the HVAC box under the glove compartment or lower dash. Remove trim panels or glovebox as required.
- Unplug the electrical connector(s) from the module and remove the mounting screws or clips holding it in place.
- Install the new module, secure fasteners, and reconnect the wiring harness. Ensure connectors are fully seated and locking tabs engaged.
- Reconnect the battery and test all fan speed positions and climate functions. Verify there are no error codes and that airflow responds correctly at each setting.
Installation Recommendations
- Always disconnect the battery before removing or fitting the control module.
- Inspect connector pins and wiring for corrosion or damage; clean or repair the harness if necessary before fitting the new module.
- If the original module failed due to a shorted blower motor or a faulty resistor, replace or test those components to prevent immediate re-failure.
- Use dielectric grease sparingly on connector contacts if exposed to moisture-prone locations.
- After installation, confirm operation through all fan speeds and monitor for overheating or unusual noises.
Why The Part Commonly Fails
Blower motor control modules are exposed to heat, dust and condensed moisture inside the HVAC housing. Common failure causes include thermal stress from high current draw (often due to a worn or sticking blower motor), corrosion of connector pins, water ingress, and accumulated debris that accelerates electronic component wear. Voltage spikes and poor ground connections can also damage the internal power electronics.
Notes For Mechanics And DIYers
This module is typically ordered by its reference numbers (P7708004 / P7708003 / 6441CQ), so include those codes when searching for replacements. The unit supplied here is without the short wiring harness; a harnessed version may be available separately if required for easier plug-in replacement.
