This '87 9000 2.0 Turbo with the early form of ACC that you cannot turn off it is either 'econ' or 'auto' when I put it into windscreen heat mode last night (HI and maximim fan speed) because the windscreen was slightly misty after the engine had warmed uip I put my hand over the vents to the windscreen and the heat was fine but the fan speed was minimal. The fan works fine and if you change to the face vents it blows like a good'uun but to the screen it is very weak and I fear for what it will be like come winter! Anything I can check for what could be causing this, and before anyone asks I have recalibrated it (auto button and face vents together). Or are all older 80's 9000's like this. Ive only ever had 90's 9000's before never this old with the older ACC. Also how do you program the ACC to set what you want the heater to be on when you first get into the car, I read somewhere you can program it to come onto a default setting automatically when you start up and it turns on.
