Heater blower

[Martinaslt]

... Grand Picasso 2015 2.0 110kw .. something is wrong with the heater blower, about 100km occur when driving, the air intake disappears when the air is switched off and reappears only at the speed of 130km ... when the shoulder is off then nothing .. I changed the cabin filters. sorry to translate the translation

From what I can decipher from the above, you are saying that the air stops blowing when you turn the fan speed down. Well this is normal behaviour. You will always get what they refer to as the air dam effect, where air from the speed of the vehicle is forced through the air intake. But closing the air vents will stop the air coming into the cabin which is not a good idea.

Just leave the system on AUTO and let the climate control do its job. It should maintain the cabin temperature at the level set automatically. The air flow distribution, and the air temperature will be done automatically. Be aware that when the vehicle enters a sunny or shaded area the sun sensor informs the Climate Control system of the sun brightness and angle which allows the climate control system to increase or decrease the air flow direction, speed and temperature automatically when the unit is in AUTO mode. So expect to feel and hear the blower motor adjusting itself.
