Heating failure

Hi everyone, how's it going? I need some help with a problem with my car. I need to know where the heater fan is located and how to get to it on my 2004 Fiat Stilo 1.9. I went to the dealership because the heater isn't working, and with this cold weather, it feels like I'm going to the mountains to get to work. They told me it's the fan and that it costs a fortune to replace, which I'm not in a position to spend money on.
I hope you can help me with this.
Thanks in advance, and greetings to all.

Hi xecue, I don't know much about your vehicle, but the best thing I can recommend is that you look at the top of the page where it says "workshop manuals," then search for your vehicle's make... the manual for your Fiat Stilo is available! That might help you solve your problem. Cheers!
