Car blower not working on all settings

The blower motor is a 12VDC motor. Its speed is regulated by passing the12VDC through a stepped resistive network that "drops" voltage such that the motor sees a lesser voltage. It's generally that network that needs replacement. The fan itself can be unplugged and tested using a 9V transistor radio battery..

IIRC, the Cruze doesn't use resistors - the control module uses pulse width modulation to get the speeds. So, if it's not the fan, it's the module. However, I do recall some reports of bad fans on here - I don't remember any bad modules. '13 LTZ.

If your AC only works on high, one possible culprit could be a faulty relay switch. The relay switch is responsible for transmitting the signals from the thermostat to the fan. If it is not functioning properly, it can prevent the AC unit from operating at lower settings.

Mar 28, 2023 · In general, car heater issues can be caused by the following: Low antifreeze. If your antifreeze has gotten too low, it means there won’t be enough hot liquid in the heater core, resulting in cold air. You should top up the coolant to the appropriate level and then check to see if the heating is working again.Symptoms Of A Bad Blower Motor Resistor. When the blower motor resistor goes bad, the motor can get stuck at one speed. The various airflow settings may also fail to work or you may not get any air from the vents. Furthermore, it can cause an inconsistent or intermittent fan speed, leaving you without proper airflow. ….

Position 4 bypasses the resistor pack completely, to take the -ve side of the motor to earth to give the highest speed. If you've checked the three resistors in the pack and none are open circuit, and the blower wont work in ANY position. Then it points to either a faulty rotary switch, or a faulty blower motor.Blower motor problem since 2,500 miles NOW at 10,000. First time they thought it was a loose connection to the blower motor.
