My 2004 Prius (40,000 miles) started displaying a message on the display screen “check airconditoner connection”. The AC is running fine. Toyota mechanic tells me that I need AC amplifier and Ambient temp switch for $860 bucks. Claims Toyta never had this problem or heard of it. If that is true what are these items? I need help, and would love to hear from anyone! Thanks, Ruta

It may not have anything to do with the AC amplifier and ambient temp switch. There has been a lot of discussion of this problem on sites like [priuschat.com](http://priuschat.com). Best to search there. In short, there is a Toyota Service Brief out on this problem (TSB EL002-05). This seems like a pretty widespread problem. Customers are paying $400 to $4000 to have it fixed. Seems to me like Toyota is not owning up to the fact that they have a defect.
