Oldsmobile Cutlass Ciera heater not blowing hot air issue on Oldsmobile Cutlass Ciera

Some Oldsmobile Cutlass Ciera owners report experiencing issues with their heaters not blowing hot air, which may be caused by a broken heater blower motor, a faulty thermostat, or a failed heater blower motor resistor. In instances where the blower motor fails, owners may notice that while the air conditioner and heater still function, the air pressure is significantly reduced. Additionally, if the heater core hoses are hot but no heat is coming from the vents, this could indicate a malfunction with the blend air door or motor/actuator located inside the dashboard. To diagnose these issues, it is recommended that owners check the hoses to ensure they are both hot and flowing properly.
