Purpose and Operation
The blower control unit is mounted in the evaporator assembly. It controls the speed of the blower by regulating the ground of the blower motor. The
signal to operate the blower control comes from the programmer.
The blower control unit also controls the A/C compressor clutch relay. This is determined by an electrical signal that the blower control unit receives
from the control head.
Use caution when removing. The heat sinks can become very hot.
