Understanding Car Heating and Cooling Problems

Car heating and cooling problems can make driving during the hot summer months and cold winter months practically unbearable. Let’s look at the common car heater problems and what you can do.

Faulty Heater Core

The heater core is a small radiator that transfers heat from the hot coolant to warm the car’s cabin. A heater core can malfunction as a result of clogging, contaminated coolant, a leak somewhere in your system, or fan-blown air not reaching the heater core. You’ll know your car’s heater core is faulty if you notice the following signs:

  • A sweet smell in the car
  • Fog inside your car
  • A chilly passenger compartment
  • Low coolant level all the time
  • Frequent loss of coolant
  • Overheating engine

A faulty heater core can be a severe issue. It can cost you more money down the road if left unaddressed for a long time. If you notice signs of a faulty heater core, call a trusted auto repair shop for help.

Not Enough Coolant

When coolant levels drop, your car’s heating system will not function properly because there won’t be enough fluid to heat the heater core. The most common reason for insufficient coolant is leaks that may come from leaking hoses, sensors, or gaskets. Driving a car with a low coolant level can lead to a myriad of expensive problems like a blown head gasket, a damaged engine block, and a seized engine.

Malfunctioning Thermostat

A faulty thermostat can be another reason why your car heater is not working. A car thermostat’s job is to regulate coolant circulation in the engine. Like other parts of your car’s heating system, the thermostat can fail due to age or get stuck in either an open or closed position. If your car’s thermostat is worn out, visit a nearby auto repair shop and have a new one installed.

Faulty Heater Fan

The heater fan blows air through the heater core into the car’s cabin. This part can malfunction due to wear and tear or break down as a result of electrical problems.

Common Car Cooling System Problems

AC Blowing Hot Air

There can be two reasons why your car’s AC is blowing hot air: a malfunctioning compressor and a faulty blower motor. If your car’s AC is blowing hot air, you should visit a reputable auto repair shop and have the issue resolved before it becomes an expensive replacement.

Low Refrigerant

This problem is usually caused by AC leaks. One of the signs of low refrigerant in your car’s AC unit is a situation where the unit blows warm or hot air when it’s set to blow cold air.

Clogged Condenser

A car’s AC condenser may become clogged over time due to the buildup of debris in the refrigerant. If any type of debris gets into the condenser, it can block the flow of refrigerant and reduce the effectiveness of the AC. The condenser may also fail due to deteriorating seals and tubes.
