it's getting cold so I was playing around with the heat, I've noticed that the higher I turn the temperature the less pressure comes from the front vents. So when I have it on low it's blows the AC cold and hard through the front vents but when I turn the **** to Hi you can barely feel the heat coming out. It seems as if the blower power shifts because I feel the heat blowing very hard from the "front Windshield" vent. Is this normal?

What happens when you manually select front vents via vent settings? Could be that it's on Auto which varies the air distribution amongst the vents.

Thanks, I got it working now. Some reason still kinda weird why it changes vents when temperature changes

The system is intelligent. It will not blow hrd if you try calling for heat before the engine is up to normal temperature.

it is normal. it tries to blow hot air on windshield to remove fog/ice. on less sophisticated cars you would have to do it manually or the windshield will fog up.

haha bye

Its because there are multiple temp sensors in the car so if the feet ar hot it will try to cool them down and if the main vent sensor is cold it will equal that out as well..
