ok, i have a 95 yukon that has no high speed on the blower motor.did some research here and ended up replacing the blower relay and the resistor pack. no luck, so i bit the bullet and bought a new control head. still doesn't work. got a chiltons manual to check my wiring. so, my question is which wire supplies power to the relay for high? in the diagram i have it looks like an orange wire. if i want to put power to just that wire do i need to ground something else?
