Hahaha! Wrong spelling mate. It's became the flower. Ahahahha.

The blower is turning all the time when engine start without the command and it's same speed. But the blower is on and off when just ignition on.

What do you mean but pulling out the blower? How can we know if the AC system working or not if we pull the blower out?

Thanks for respond mate!

The fault keep asking me to check the cable and supply to the regulator blower and I can see all are supply correctly. Once I replace the new regulator then it did not make any change.

All three codes does not point out to check any other area beside the regulator.

Hi! i have checked and it is connected well. In the actuation data it is also showing correct temperature of current temperature which is about 29 degree.

Do we need to do any adaptation when replacing the new blower regulator mate?

This car was hit by mototorbike on the front right door and it should not affect the AC system... I cannot understand that.

All fuses have been checked. Nothing can condenser as faulty cable or fuses. Rear blower working as normal and give ok value.

Front blower cannot control and the blower motor working and stop working itself. Speed control cannot change, AC compressors is not engage. B82 interior humidity sensor is not possible to find.

Anyone can help!
