Hello, my car is 508 THP SW 2011 model. It has been 1.5 years since I bought my car second hand, but I just thought of checking the cooling of the glove compartment. There is no air from where it should come. I open and close the control valve manually, but nothing happens. Neither hot nor cold air is coming into the torpedo. What could be the problem? Is there any intervention I can do on my own?
