The air conditioning regulator does not work for me

It is correct will work the four ventilator speeds and the resistance is between the fan and the evaporator of the A/C sige the ventilation flow because this piece is cooled by the same ventilation there is no way to get lost. You will recognize it because of this resistance four or five cables come out

Thank you but it is that mechanics are little and I beg you to be patient with me.
You can explain Mejos to have if I clarify the resistance is behind the regulator because since everything is so compacted I do not know where to look and I also do not know where the evaporator is.
I would appreciate you very much that you indicate me

Well, the easiest way is to locate the fan, from this two cables leave and where that is the resistance of speeds you are looking for must be held by one or two pijas

Sorry but I'm going crazy, having:
the speed regulator, under the radio of the car is worth? It disassembles it and there is a connector that connects the regulator, the air conditioning switch is that?
I can't see the fan with the naked eye when he starts from the bodyguard which is impossible to see it.
Is the resistance where the air outlet rack from the habitaculus?
Or is it in the regulator itself?
What do you find?
Many grapes for help

What else can I tell you, Gaudencio05 has already told you everything, just pay him and everything will work out
