Does Your Car Blow Cold Air in the Winter?
If your car is blowing cold air during winter it doesn’t necessarily mean that you require major auto repair. Understanding how vehicle heaters work can aid in diagnosing if your vehicle heater has a problem or if you just need to let your car warm up a while longer.
About Car Heaters
A car’s heating system heats up the cabin of your car by essentially using the heat coming from your engine. If you don’t feel warm air coming out of the heater, it may just be that you need more time to let your vehicle’s engine warm up before driving.
There are two different designs for car heaters, an Automatic Temperature Control System and a Manual Control System. The manual system needs to be adjusted by a driver or a passenger in the car, and the automatic system is run by a computer. Your car’s heating unit controls the blower motor, temperature controls and blend doors. It’s a good idea to familiarize yourself with your car’s heating system, for when it comes to troubleshooting issues.
Potential Car Heater Issues
When blowing cold air during winter as opposed to warm air in your vehicle, there are a few things to check out going in for repairs.
- Your thermostat could be stuck in the open position
- There might be a coolant leak causing a low coolant level
- Your car’s blower motor or heater core might be plugged or leaking
- Your heater blower is not working properly
- Your vehicle’s blend doors may not be working as they should
If you experience severe cold weather often, it’s wise to have your vehicle’s heating system checked before winter begins.
