Question1998 Toyota Avalon v6 mileage: 100k. Without warning, the air conditioner & fans quit working. This car has an outside air temp display & it suddenly does not show a temperature reading. I checked every fuse I could fine with a meter. All ok. The car starts & runs fine & all other electrical works ok, i.e., lights, rear defroster, windows, door locks, seats. It is equipped with an auto mode for the air with a temperature adjustment that will control the blower speeds. This is not working, or if you try to punch manual blower speeds, (each button will light up) but will not turn fan on, or if you push the ac button, will not work or light up.
AnswerI am not that familiar with Toyota, But from what you stated, I would tend to believe that your problem lies within the A/C heater control module, If applicable to your type of vehicle.
I wish I could me of more help but Toyota is one that I am not familiar with.
