O.K., #4 on your switch gets full voltage & that why it works still. # 1 2 3 speeds work through a resistor w/ 3 diff. Size resistors that give them there slower speeds. This is located in blower motor case b-hind glove box & not a timely or costly repair. If someone tells you it is continue looking for honest tech or shop. GOOD LUCK !
