BMW: 2001 525i AC/Heat Blower not working, fan work, blower motor

Question
Hello, my A/C always works fine however today i turned it on and no air came out the vents. The lights for A/C and Circulation came on when you turn the Fan controll button to the on postion (clockwise from 0 mark), i also try turning the heat on and nothing came from the vents. please tell me what are the possibilties and where to look and check for problems. Thank You

Answer
Dame,
 Does the fan work?  or are you saying the air is not blowing hot or cold?  

 If the fan quit, it's probably the resistors on the blower motor, or the motor itself is shot.  I would have a trusted mechanic check it out, sounds like it could be several things
