Dear R129ler I have a problem with the operation of the air conditioning – my car is a 320er Mopf1, year 1996. At first the system was empty – plant was pressed with nitrogen and then filled. Now I have problems to turn on the air conditioning, to operate. Thanks for every tip. Another observation – there is no air from the middle nozzles. And the middle nozzles can not be switched on separately (with the switching) The display only works if one of the two switches at d It’s very strange everything – somehow adjusted or defective. And still something ……must the air conditioning be kept in place with it also the Yviscolfans run? Or does it just have to be “functional”? I think if you drive openly your climate also shuts down, right?!? Is there advice, can anyone give me tips?
