The ventilation runs only on 4, is of course annoying (loud) and in the weather it is with the air conditioning, later with the heating quite annoying! I already know, pre-resistance or thermal protection! Now my question: Where is the plug with the resistors and the thermal protection? Have already removed the glove compartment box, but unfortunately I did not find it. The interior filter is ok, I changed only in winter, seems to me like everything very installed and working in the narrowest room is also not so sparkling at my age! Now please my question: Where is the plug with the resistors and the thermal protection? On the passenger side or the driver side? Can one recognize the plug? (cable white / blue)? Is there a trick? Have the model with the climate (or did all the splash)? Thank you for tips!
