The original complaint was for the AC, The TSB is not listed under HVAC or Radio on Shop Key so I wasted some time checking out the HVAC controller before googleing the problem and found the TSB that way. It is listed in Shop Key but it is under the instrument cluster heading. You can buy refurbished units for around $450. I replaced this one with a used unit for around $100.
This describes my problem with my 2004 Prius with one exception. My display looks and acts just like the one in the video until the radio "shorts" out. I can turn the radio on manually, and after a while the radio will cut off and then both the radio and temperature displays will work just fine. Could this be a problem with the radio connection?
