Question edited for clarity.
Question moved to model category.

Crankshaft sensor is definitely located next to the crank pulley (drivers' side, RHD). Reasonable access after removing front drivers side wheel.

When the Automatic Climate Control is set, you are no longer in control of settings and fan speeds. The sensors make the unit run at full speed and don't power down until the set temperature is reached. If you have the temperature set to 18'C (Max Cold), it is likely to never achieve that. If you want to take control back, you need to take it from Auto, to Manual. If it still does it, you need to go to an auto electrician who will use a pro grade scan tool to check on communications to the Body Control Module and the sensors controlling AC, Heating, and Fan Speeds.
