Peugeot Partner interior fan does not work

Greetings to all foreros. I have the following problem: the interior fan of my Peugeot Partner does not work, they have told me that it is the regulatory circuit, but I do not know where it is and how to disassemble it to suck it for one of some scrap, is that there is a lot of crisis. Thank you all

Hello first, find the heating engine that is the one that you have problems, one thing does the companion seat at the back, reclines the backrest, go down in the head with your head under the board, there is the engine, take out the three screws, take out the engine outside, looking at the engine shovels below is the platelet with speed variator, take it out and repair it. Platelet, you really have to change the platelet but it is more economical to change the transistors I hope my help is good
