Replaced blower motor but air is still not blowing through air vents on 1990 BMW 735i

The air isn't flowing throught the air conditioning vents is there something we can try other than replacing the blower motor?

Have you checked fuse #19 (30 Amp)see that you have power at the green/black wire at the motor with the key on, the second wire gets grounded to operate the blower motor but you need a wiring diagram to trace the controls circuit.
