Cruise control/air conditioning/brakes it's a lot I'm French,my car is in France

What is your question?

Hello The electrical part works, I see a second, "cruise" on the dashboard, but the CC under the hood does nothing, I can crush it with one hand, and I hear the sound of a smoker's lung. If anyone can help me, I stay in KY (Morehead) until July 15 I will speak about the air conditioning later, but it is not easy because English is not my mother tongue. Thank you in advance
