Where is the heater blower unit in your Volvo V40 2003?

In a 2003 Volvo V40, the heater blower unit is typically located under the dashboard on the passenger side of the vehicle. To access it, you may need to remove the lower dashboard panel and possibly the glove compartment. The blower motor itself is mounted to the heater assembly, which is connected to the vehicle's climate control system. If you're troubleshooting or replacing it, ensure the vehicle is turned off and disconnected from power for safety.
