I'll try to make this short and sweet. The speed control on my climate control panel only works on the highest speed but not any of the others. After reading I'm pretty sure its the resistor that needs to be replaced but in the event that it is not and the whole panel needs to be replaced can the original part AC Delco 15-73933 be substituted for AC Delco 15-73064 and it function just the same??
