The dealership is telling me that my AC amplifier needs replaced cost over $1500

What is your question?

My A/C compressor and clutch were replaced about 3-4 months ago and then about 2 months later at idle or slow moving traffic my AC would not blow cold air. I would turn off the AC and back on and it would work. This lasted for several weeks until it would not blow cold air at all. The dealership is telling me that my AC amplifier needs replaced and it cost over $1500? Does this sound acculturate?
