Just because it's cheep and might not be the real answer, you might want to try it. Reset the temp control computer. I believe it is done by holding the OFF and AUTO button at the same time. Either way good luck. scot Alan Edwards Replace nospam with xnet wrote: > I have a 1996 900 SE Turbo and for the past 6 months I've been noticing > a problem with the Automatic Climate Control (ACC) System fan. > Sometimes I'll get in and want more air volume and when I press the up > button to increase the fan speed, the bars on the fan speed display > moves to show that I've selected full fan but, the fan doesn't increase. > If I leave it that way it will eventually go to full fan speed, but > sometimes it takes anywhere from 2 to 15 minutes or more.
