ive got a 2000 Tahoe LT that has a inop. rear blower. The resistor was fried (i replaced). Im not getting signal from the purple wire to the resistor. I checked continuity to the 2nd row control unit from resistor (its good) , and continuity to the front control unit from 2nd row unit ,purple with white stripe, (its good too) all fuses are good but it seems the control system isnt getting power.
big orange wire at resistor is 12v and will power blower if i jump black and purple signal wire. What should i check next.? thx
