I have no answer, however I have the exact same problem... I never know when it is going to blow... sometimes I will drive for miles and it will just start blowing again
Could be several things, blower motor, blower motor resistor, control head or the wiring. It will need to be diagnosed to know what the problem is, better take this to a shop if you cannot perform these tests yourself.
