If the blower motor not blowing,and it is on high, bump the lower motor to see if it will try and start working again,if it does,replace the blower motor.If it does not,then replace the blower relay.If this only happens on the lower speeds,replace the blower motor resister,witch is mounted very near the blower motor in the blower box,with two screws,and about 7 wires going to it.
Brushes on the motor may be going bad. Blower motor is in engine compartment under wiper motor assembly. The blower motor regulator is under the blower motor. There is an A/C relay behind the fuse box under the screwed down cover.
for lack of motor speed its probably the brushes on the motor or the regulator. If no cold air your charge is probably to low to engage the compressor.
