General Fiat punto Cabin fans not working

[TrAsHCN]

Hi!
I have a question about my cabin fan that is not working.
I have checked the fuze but i dont know if it has a relay for it.
The fan itself works the resistor too and the knob for the fan speeds is new.
The battery is fine because the car turns on and drives no problem with all of the other accessories working fine except the cabin fan.
The exact car is: Fiat Punto 1.2 16v Dynamic 2004
I have ran out of ideas so i dont know what to test anymore cause everything works outside of the car but not when its plugged inside and installed correctly.

Does it have a relay and if it does where is it?
Can ignition switch be problem?

Any help will be appreciated.

The fan has a black relay. Relay 8 in the engine fusebox. position diagram is inside the fuse box cover

The Dynamic had aircon. 90% of people don't bother changing the cabin air filter. The motor for the fan has to work harder to push the air through the clogged filter and so the current draw goes up and the wiring gets hot and burns out.

If you have checked all other components then the only obvious remaining solution to the problem is the wiring itself has burnt out. Id start doing continuity checked between the fan and the resistor pack, the resistor pack and the controls.
