How to Remove the Blower Motor of BMW 740?

[McAnthony]

The blower motor of BMW 740 is located in front of the co-pilot's seat, below the front windshield. First, remove the lower windshield panel to reveal a relay rack. The blower motor is situated beneath the relay rack and has two plugs. Simply unplug them to remove it. There are two consequences if the air conditioning blower motor fails to work: 1. The air conditioning system cannot function normally. No air will come out of the vents, and although the fan speed is displayed on the screen, no air will blow out regardless of the setting. 2. The temperature at the evaporator box becomes too low. A non-working blower motor can cause icing, leading to damage of the evaporator box.
