In summer...if the interior is really hot and you have the IHKA in AUTO mode...the blower will usually go to a higher speed due to the solar sensor registering high heat inside the cabin...so the blower will usually turn up to high to help move air through the cabin which is helping in a thermal dynamic way (helping to dissipate radiant heat from the seats/dash surfaces)...as well as trying to get the cabin to the set temp on the display as fast as the system can. Once the cabin temp comes into range, then the fan speed will slow down.
See info below on how the e38/e39/e53 w/solar sensors affects the IHKA operation when in AUTO mode (the e38/e39/e53 models w/solar sensors have the IHKA control panel with the MAX button):
