01 Sierra Cruise & Blower Motor Question

Hello again,
Cruise not engaging, I have replaced the brake switch but that did not fix the problem. Fuses are ok, manuel states that 3 wires at the plug going into the servo control should be hot. I'm getting juice at only 2 of them. Should I be looking anywhere else? Also, blower motor operating on only the 2 highest settings. Shouls I replace the switch or the blower motor.
Thanks in advance for your help

Thanks chevyguy, the resistor pack was the problem. I did a ohm's check on it and found resistance on 1 pin only. $29.00 for a new one at the dealership. works great.
