:banghead: I have a 1991 525. When i turn on the AC/Heater I can hear the fan blowing but no air comes out. Any suggestions?

Thanks!

Are the vents open? Rotate the control on the vents to open them. Obviously, I had to ask. other than that, there are "motors" that open and close various ducts inside the vent system to redirect the air to different outlets.... defrost, floor, and ac vents. On my 89 525 there are slider knobs that open these vents, one for floor, one for defrost, and one for ac vents.... mine have to be pushed to the right to open up the vents.... Start by checking all fuses related to the climate control. good luck...!
