Is the HVAC control module the same as the original component?

The control module receives input from the HVAC control module and is a GM-recommended replacement for your vehicle’s original component. This original equipment HVAC blower motor control module has been manufactured to fit your specific GM vehicle, providing the same performance, durability, and service life you expect from General Motors.

What is ACDelco GM original equipment HVAC blower motor control module?

ACDelco GM Original Equipment HVAC Blower Motor Control Modules are microprocessor computers that modulate HVAC blower speed. The control module receives input from the HVAC control module and is a GM-recommended replacement for your vehicle’s original component.

How is the speed of the blower motor controlled?

The electronic module that controls the speed of the blower motor is called a blower motor control module. In some cars, the blower motor has only 4 or 5 fixed speeds. In this case, the speed of the blower motor is controlled by a blower motor resistor.

Where is the blower control switch on the dashboard?

The blower control switch on the dashboard controls the circuit flow of the blower motor to adjust the voltage from low, to medium, to medium-high, to high. When on high, the circuit bypasses the blower resistor.

What does a blower motor do in a HVAC system?

A blower motor is a mechanism that allows HVAC systems to distribute heated air. This piece of equipment makes it possible for structures of all sizes to maintain a comfortable indoor climate.

Why is the blower on my GMC not working?

A few brief tests revealed the Blower Control Module had failed and was not providing power to the blower motor. Gm vehicles with digital climate control use a Blower Control Module instead of a Blower Resistor to control power to the blower motor. Failure of this module and it’s manual HVAC counterpart the Blower resistor is common.

Why does my AC fan control module stop working?

Since this relay works the blower motor as well, you may notice that the air flow in the cabin of the vehicle is significantly reduced. The module helps to regulate how hard the blower motor works when needed, which is why it will cease to work with this part.

How does a furnace blower motor relay work?

The blower motor then pulls the warm air out of the furnace and powers a fan that pushes heated air out through vents and into the structure’s rooms. There are two main types of blower motors. Single-speed units operate on an on/off switch. These motors operate at a consistent speed until the desired temperature is achieved.
