Blower Speed Controller
CAUTION:
DO NOT operate system with blower motor disconnected, as it may damage blower speed controller.
Blower speed controller is located on evaporator case, near blower motor, in engine compartment. See Fig 1. The controller converts signals from the EATC module to a variable ground feed to the blower motor. Blower motor speed is controlled by EATC module and blend door actuator position. A delay function provides gradual increases or decreases in blower motor speeds.
