At Nelson Auto Repair, we know how frustrating it can be when your car’s heat suddenly stops working, especially when you’re depending on it during the colder months. There are a number of reasons why your heat may not be functioning properly, and understanding the root cause is the first step to getting it fixed. Let’s explore some of the most common reasons for this issue and how we can help resolve it.
Common Reasons Your Car’s Heat Stopped Working
Low Coolant Levels
One of the most common reasons your car’s heat stops working is low coolant levels. Coolant (or antifreeze) is essential not only for regulating your engine’s temperature but also for providing heat to the cabin. When the coolant levels drop, there may not be enough circulating through the heater core, which prevents warm air from blowing into your car. At Nelson Auto Repair, we can check your coolant levels and inspect for any leaks that could be causing the drop.
Faulty Thermostat
A malfunctioning thermostat is another common culprit when your heat stops working. The thermostat controls the flow of coolant to your engine. If it’s stuck open or closed, it won’t allow the engine to reach the correct operating temperature, which can prevent your car from producing heat. Replacing a faulty thermostat is a straightforward fix that can restore warmth to your vehicle.
Clogged or Leaking Heater Core
The heater core is responsible for transferring heat from the engine’s coolant to the air that flows through your vents. If the heater core becomes clogged with debris or if there’s a leak, the heat won’t be able to make its way into the cabin. At Nelson Auto Repair, we can flush or replace the heater core, depending on the severity of the issue.
Broken Heater Blower Motor
The blower motor is what pushes the warm air from the heater core into your car’s cabin. If the blower motor fails, you won’t feel any air coming out of the vents, even if the heater core is working perfectly. If your heater isn’t blowing air at all, the blower motor could be to blame, and we can quickly diagnose and replace it if needed.
Faulty Heater Control Valve
The heater control valve regulates the flow of coolant into the heater core. If this valve is malfunctioning or stuck in the closed position, it prevents coolant from reaching the core, which in turn stops your car from blowing warm air. Our team at Nelson Auto Repair can inspect and replace the heater control valve to get your heat working again.
Air Pockets in the Cooling System
Air pockets in your cooling system can also be a reason for the sudden loss of heat in your car. When air bubbles are present in the coolant lines, they block the flow of coolant to the heater core, leading to cold air blowing from the vents. Bleeding the cooling system to remove trapped air is a common solution that we perform at Nelson Auto Repair.
