V70 XC AWD L5-2.4L Turbo VIN 56 B5254T (1998)
NOTE! The blower fan's speed control (air flow) when the blower fan speed selector switch is in AUTO position can be reprogrammed. The air flow
can be increased or reduced by a maximum of 8 liters/second (17.8 cubic.ft/min) 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.
Use the Programming function to read oft and program the ECC control module. Programmable blower fan speed is: between ± 8 l/s ( ± 17.8
cubic.ft/min) in 4 l/s (8.9 cubic.ft/min) steps.
Read off blower fan speed programming. Make a note of the reading. Program as necessary.
Then operation is done.
