Blower Fan SPD

WARNING: This page is about a different car, the 2002 Volvo C70, 2001 Volvo C70, 2000 Volvo C70, 1999 Volvo C70, and 1998 Volvo C70. However, it is still accessible from the selected car via links, so may be relevant.

The cabin blower fan speed (air flow) can be programmed when the blower fan switch is in the AUT position. The air flow can be increased or reduced by a maximum of 8 liters per second from the normal setting.

If the control module is programmed for a lower air flow, this will result in slightly lower noise levels in the car, but also in slightly reduced air circulation. This can make demisting the windows less efficient.

If, however, the control module is programmed for a higher air flow, this will result in slightly higher noise levels in the car. It will also result in increased air circulation which can make demisting the windows more efficient.

Positive value = Increase speed (flow).

Negative value = Lower speed (flow).

Each step is the equivalent of an increase or decrease of the air flow by 4 liters per second
