I have 99 323i 5 speed manual and my blower motor recently gave out. At first it would work and then cut out at random until it finally stopped working completely. My first attempt at fixing this began when I replaced my blower motor resistor, but the fan still wouldn't start. I then replaced the blower motor assembly including the fan and it still will not push any air through the vents. Is there anything else I may be overlooking that might be causing it not to turn?
