No, air con should be separate, should not affect blower motor
Are the fuses OK?
Does the display show an increase in blower speed when selecting
a higher speed?
Could be a blower motor problem (worn contacts in blower).
Are the heater flaps working correctly?
You'll need to do some digging around to eliminate things.
Start with the fuses, then remove glove box to verify power to the
blower motor. If no power at the blower motor, apply power & ground
manually / direct at the motor, to see if the motor itself is OK.
