My old man says don't worry about it.
I noticed this clicking noise about a week ago when I pulled in the garage with my windows down. If I put the vent on upper or upper lower, I can then turn the A/C on and off. Everytime I do that I hear the loud click. The old man says it's just a switch turning the compressor on and off, and that all cars work like that.
When it thinks it is cold enough, it turns it off. WHen it gets hot, it turns it on. The problem then when I come to a stop with the windows down is that it goes on, produces cold air and sucks it in. Then it thinks it is cold and goes off. But having it be so loud and continue on and off, on and off, basically nonstop in 20 second intervals seems wierd to me.
Does this sound like the same problem some of you are having or are you talking about something completely different?
