My climate control fans surges and then drops off on my 2001 330xi. It seems to happen when I'm either using auto control or when I'm using the manual controls. The current temperature here in Philadelphia is around 50-70 degrees Fahrenheit. I'm seeing the problem with the heater/cooling fan surge at all temp settings....it seems to come and go. Any thoughts. Could it be a filter? I'm perplexed because it comes and goes, but seems to happen most of the time when I'm driving (especailly when I slow down, for example). Thanks!
