Pontiac Grand Am Problem Report
Pontiac Grand Am Loss of One or More HVAC Blower Motor Speeds
The HVAC blower motor may stop working at one or more speeds due to a faulty blower motor resistor block. Our technicians recommend to confirm the resistor is at fault by first checking the operation of the switch.
