Heater blower speed not working

Good afternoon all,

I’m hoping that I may be able to get a better idea of an issue I’m having with my 2013 Leon.
Last Friday the speed function on my interior fan just stopped working. I firstly swapped out the 40 amp fuse but still no luck.
The vehicle has since been to a garage who have replaced both the blower motor and the resistor but still no luck.
The blower motor seems to be working fine as it has 12volts and is clearly blowing a trickle of air out but does not increase.
Strangely today once I have turned the ignition off the fan is still running so I have had to remove the use to stop this.
I was hoping it would be a much easier fix and not cost a lot.

Does anybody have any ideas please?

Thank you in advance.
