    I have almost no heat or A/C. Coolant and oil temp seem normal. Fan works (low thrust). I suspect that the interior temp sensor could be the culprit. Any hints or suggestions ?

    Connect a diagnostic computer to the system to see what the temperature inputs and outputs from the control unit are.

    So does it or doesn't it blow cold/hot air? if you can scan it.. go for it as above.

    My bet would be on the control unit going. Mine suddenly didn't blow ac. Turns out Control Module was bad. Getting more common as these cars age.

    It may be the TGK Valve Part # 65066400, it is located under the removable access panel under the hood. My mechanic said this is a common problem with the hot/cold air not reaching the desired temp inside the cabin.

    How long have you owned this car ? I thought I had a problem with my heat also until I read that the stop button needs to pushed in for the heat to work. After I pushed the stop button in I had heat! Hope your problem is solved this easy.

    On my car, it's the other way around. The stop button has to be out for the heat and A/C to work.

    You are correct , took the car out today and realized it has to be out for heat to work . Very confusing ...

    Thanks for all the replies. I released the A/C stop button and I now have great heat ! Feeling dumb I referred to the owner's manual and it states "Pressed (stop) The air conditioning is turned off. The heating is still enabled though and will function according to the temperature set."
    I am guessing that I still have a malfunction but I can continue to drive at least until it needs to go in for other service.

    Don't. My first Ferrari I didn't know that either. The only time I push it in is for track days. :)
