hi there! my internal air circulator stops to function without reason. I have checked the fuses and the relays and everything is ok. what is wrong?

and the air conditioning is in fault too, everytime I press the button the fuses always crack

Internal blowers are prone to failure... sometimes hitting it helps. But probably the electric motor or connector is causing these problems so check that out

I will go to an air conditioner repair center to verify it and post here later the solution
