Checking Programming, Blower Fan Speed (ECC)

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.

NOTE: 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/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 result in reduced air circulation which can make demisting the interior glass more difficult. If, however, the control module is programmed for a higher air flow this will result in slightly higher noise levels in the car, but also result in increased air circulation which can make demisting the interior glass more easier.

Ignition on.
Use the Programming function for to read out and program the blower fan speed.
Read off blower fan speed programming. Note down the value. Then program the blower fan speed.

HINT: Increased blower fan speed (air flow) gives more ventilation and higher noise levels.

HINT: Decreased blower fan speed (air flow) gives reduced ventilation and lower noise levels.
