What's your VIN?, it may be integrated into one of the modules.

Ok so you have single Air Conditioning on this model.

I would suggest a diagnostic to obtain the fault code so that you can better ascertain the specific problem. There are quite a few listed.

You only have parts: 1, 2, 3. 4. 6, 8 & 9 on your vehicle.
No 3 is the Heater Motor Control Module.
It is part number 6441 CE.
In this Diaggram, item 10 is the air heating resistance - so I hope you didn't change that as it won't affect the motor.You have heater control variants 3 & 6.

This is the actual Heater Module Blower Module attached to the Blower Motor.
Without a diagnostic to help pinpoint it, there's no way to know for sure whether the fault is in the control panel on the dash or the blower module itself.

I expect if there is any thermal fuse, it will be integrated into the control module.

So you really need to get Lexia on it to help determine where the problem is. You may have a problem elsewhere, like the engine fuse box.
