The blower fan is an important component of the air conditioning (A/C) system on the BMW E46. If the blower fan begins to malfunction, air will not flow out into the interior passenger compartment. Thankfully, removing the blower fan is fairly simple and should only take two hours or so to complete. Once removed, you can repair the blower fan or even replace it completely.
