'99 Acura TL -- I also have a temperature problem although it sounds slightly different than the original post. I cannot cool my car without setting it to the lowest number nor can I heat it without setting it on the highest number.

It was cold last night, for example, so I had to set the heater to 90 in order to warm the car.

Any ideas? My deal can't figure it out, but I have little faith in their green techs.
