I do not own a GS400 but a friend has one. She is in another state so I can not diagnose the car directly. She claims that the heater and ac do not work as they should but that the problem seems to be that the Navi buttons do not work. She claims that all the other navi functions work (radio, maps ect...) She says that the blower blows hot air and she can't control the temperature. Does this sound like a sevo issue or something else? I searched and it seems most servo issues are hot on one side cold on the other, Any opinions? Sorry I don't have better details but its all I got. Its a 1998 GS400 with Navi
