Blower Motor Control Module

Blower motor control module is located at the bottom of evaporator module, left of blower motor. Blower motor control module receives signals from A/C-heater control panel which are amplified into strong output signals. Blower motor module is transistorized and provides variable blower motor speeds.

In manual mode 2 blower speeds are provided. In automatic mode, 3 blower motor speeds are provided. A feedback circuit is provided to confirm blower motor speed. When heating is required, blower motor operation is delayed until engine coolant reaches adequate temperature to provide heat. Blower motor operation will not be delayed during defrost operation or with manual blower motor speed control.
