does nothing
- no increase/decrease in airflow speed?
- no increase/decrease in output temperature?
- no aiflow at all?
- no forward movement of the vehicle?

nothing is such a powerful word - what do you expect it to do and what it does do?

can you be more specific, pleae?

you turn the engine on, you look at your digital temperature readout (it is not a read out of your temp in the car, it is the "order" you are giving the system to establish the indicated temperature), you see 75* F, and fan speed indicator at the lowest setting.
you push the "+" to increase the speed of the fan and....

you push both of the blue buttons to draw temp to 60*F and...

you press the button that say "AUTO" and ...

you press the snowflake symbol "*" and...

you move the stratospheric (some funky name, isn't it??) dial that has red/blue markings in the middle of the central vent up and down and...

Air Supply
 

When I push the fan speed indicator + the fan speed does not increase although the bar indicator does illuminate and increase to show flow there is no flow from the fan. I tried the auto button, still no air flow I checked both fuses F38 & F48 for the climate control and they have not been blown ??

do a search for final stage resistor pack - see if you find anythnig that corresponds to your issue...

FSR. Replace with an OEM part only. Many posts on here of NON-OEM FSRs failing after only several months. I put 2 e-bay FSRs in mine within 9 mos (seller supplied replacement no charge), and BOTH failed, went with a BMW dealer sourced FSR and it's been fine for over 2 yrs.
