HEATING/AIR APTORY DELITLE THE FACIB

People, a couple of months ago, I bought a Peugeot 106, and I realized for the smell that cooked the fuses, all who had to do with the calefa fan, air, ventilation. I tried just by walking the fan and this was the problem. Now, take it out and I will see if I get the coals to change them, see if I can also disarm the bushings. But will this be the problem? or can this be the circuit? I hope you can give me a hand. Thank you !!
