the acc on my 1997 900 se turbo is behaving strangely. the indicator for the rear screen heater will come on and presumably the heater itself, then warm air comes from all the vents. this can happen at any time of day or night, rain or hot sun. is there an automatic sensor for the rear screen? and if so, where is it located. if there is no sensor, does anyone have any idea what could be causing the problem. regards
