2008 grand Picasso VTR+ internal fan blower realy slow speed

[Nutt121]

Hi all, I have an issue with the internal tan motor not working when fan speeds increased.

I replaced the resistor once before back in October 2022 and I’ve just dropped the fan down from the housing and started the car and the fan is spinning on low speeds. Even when the fans turned off it’s continuously running.

Is there anything else I can check or do to try and resolve this issue I’m facing.

Also if anyone has had any issues with this code I would be most happy for the assist. I have replaced 2 yaw sensors and none of them are working.

Fault In The Calibration Of The Longitudinal Acceleration Sensor
Impossible. Calibration *1

Any help is greatly appreciated
