Air cuts on and off when stopping or reversing

BMWORD · 02-01-2010, 11:53 PM

Like the subject states, when I start my 06 325i the air turns on and when I put it in reverse the fan speed dips way down for a momment and then goes back to the original speed. Also if I'm slowly stopping and give it some gas it happens again, this occurs everyday at the beginning and end (parking) of every trip. It is on heat right now, but I'm pretty sure it does this with ac as well. Seems directly related to giving it gas (at low rpms) Is this normal?
