Megane 99 heating

Do not heat what the hoses that go to the heating radiator are hot but the air comes out, brings some tap? If so, I can't find it, the temperature control is maximum and only moves a gate. The engine temperature is normal with its thermostat that opens and closes well. The air conditioning works well and does not turn on when the heating is how it has to be. I can't think of another ...

When you toured cold there is a steel cable that activates a tap closes the motor passage to the heating radiator and when you turn heat, the tap opens.

In some cars you have to get all the furniture from the radio, but that Megan looks on the driver's side in the engine near the steering wheel, you will see an air input that is the abitacle filter. I don't know if there is the tap, if you don't have to get out of the driver's feet.

That or put a radiator circuit cleaner to see if it is full of shit. 9 euros or there is clean the engine circuit and heating.
