Look for loose plastic trim around the exterior edge of you windshield. For years, I would get a wind rattle at 50 mph whenever I was next to a big rig. The noise came straight through the center vent. Something about the physics of aerodynamics would lift the plastic trim at the base of the windshield. After a 50 cent plastic rivet, the wind rattle was gone. Another thing to check are the rubber jack points under the sills. if one or more of these are missing the wind will enter the body at this point and appear as wind noise at the windscreen. I had this problem and confirmed this by using tape to cover over the hole and went for a spin down the motorway. that's the cheap fix, the rubber mounts from BMW were a bit too expensive for me.

If the blower works on the defrost mode only, you could have a disconnected vacuum supply line coming from the engine. If the blower motor doesn't work on any mode or speed you could have a blown fuse, burned out blower motor speed resistor, bad switch or a bad blower motor.
The blower motor fuse has blown or the blower motor itself has blown. Change the fuse or replace the blower motor itself and you should be good.
