How do I reinstall the completely set of my Air Condition

@mayorclassic can you please restate your question? We don't understand what you are trying to accomplish. It sounds as though you are having problems with the air conditioner in your BMW, but it's not obvious what you think the solution should be.

Without more information I doubt we will be able to help.

And please add specifics about your car; the year and model at a minimum.
