I have a 2005 E53 4.4 X5. I recently had a battery issue, and after replacing the battery I have no blower for the climate control system. The display for the controller seems to be working but no AC or heat. I forget the fuse numbers but I checked both, according to the owners manual, and both are good. Previously the blower motor made noise if I made a hard turn but no other issues. Is there a way to determine if the blower is getting power or not?
