My 2007 had the front blower fan motor stop. The fan speed bars would change but i had no fan. On the e70 it is pretty easy to pull maybe 8 screws to then wiggle the blower and fsu down and out from the passenger side foot well. I discovered the motor bearins were rusty and hard to turn. I lubricated with penetrating oil and spun and they loosen up. Put it back in and it has been working fine for a month now.
