Peugeot 306 '99 heating does not work

Hello, the first thing to give thanks for helping us solve this type of doubts.

My problem is that yesterday I left the hot air passage given and turned off the engine, the next day when it starts it did not come out of air, try to change the outer passage and then interior but the hot air does not work and in these cold days at dawn it shows. I have also proven that by pressing the AC button does not work either. The radio located above and the clock below the heating controls work. Could you please help me/guide me to solve this problem ???

Greetings and thank you very much in advance.

Hello, if the heating does not work, it can be to melt the fuse.

I think the fuses in the same way and after discarding them we talk about something else, for example, many kisses pass that the ruling potentiometer is cut and only works in an end diet at the fourth speed.

Ok, thanks, I will check the fuses and I tell you.

Ok do not hesitate to ask any questions
