Where is the blower located on the BMW e66?

BMW e66 blower is located behind the glove box on the passenger side. Function of the blower: The function of the car blower is to blow the cold air from the air conditioning evaporator or the hot air from the heater core into the car. Composition of the blower: It mainly consists of the following six parts: motor, air filter, blower body, air chamber, base (also serves as an oil tank), and oil drip nozzle. Working principle: The blower operates with an eccentrically placed rotor inside the cylinder, and the change in volume between the blades in the rotor slots sucks in, compresses, and expels air. During operation, the pressure difference of the blower automatically delivers lubrication to the oil drip nozzle, which drips into the cylinder to reduce friction and noise, while also preventing gas backflow in the cylinder.
I've been working in auto repair for many years. The blower motor location on the BMW E66 is right behind the front passenger footwell, to be precise, in the area beneath the glove compartment near the firewall. For removal, you'll need to take off part of the footwell trim or the entire glove box assembly first to get direct access to that fan-shaped component. The blower is responsible for pushing the HVAC system's cooled or heated air into the cabin - if it fails, you'll get absolutely no airflow, which can be particularly frustrating during hot summers. During repairs, I always disconnect the battery negative terminal first to prevent short circuits or electric shocks. With the E66 being an older model, its blower impeller may seize up or accumulate excessive dust, causing loud operation or complete failure. Regularly checking the blower motor bearings for wear and cleaning debris like leaves from the blades can prevent motor overheating and burnout. The removal process just requires basic screwdrivers and pry tools - the key is patience and avoiding forceful pulling on wiring harnesses.
