Even Texas can get chilly in the winter, and having a working heater is a must. It’s a lot harder to drive when you’re shivering and your hands go numb. If your car is having heater issues in Lubbock, TX, bring it to a repair shop as soon as possible.
Here are the most common reasons your car might blow cool air instead of heat:
- Problems with the heater core: Your car’s heating system functions like a radiator. The brass or aluminum tubing carries the coolant in and out, while blowers disperse the heated air into your car’s vents. If the blower motor is out, the coolant is blocked or there’s a problem with the coolant traveling back and forth, the heater won’t function properly. Watch out for an overheating engine, a sickly-sweet odor, fog inside your car and, of course, not enough heat. If you’re going through coolant quickly, that can also indicate a problem with the heater core.
- Not enough coolant: Your car’s coolant is responsible for transferring heat from the engine inside your car, as well as blowing cool air into the cabin when you’re using the air conditioner. When you’re low on coolant, the heat transfer cannot occur, and your car will continue to blow cool air even after the engine warms up. Take your vehicle to your mechanic if you notice this happening.
- Broken controls: If you don’t have a heater core problem, it may be an issue with your heater’s controls. Sometimes they break or clog, so your car doesn’t get the message to supply hot air. Alternatively, you may have a broken heater control valve, which is responsible for turning the heat on and off.
- Water leaks: Fluid leaking from your car is rarely a good sign. If, in the winter, you notice puddles of water underneath your car, there may be a water leak. First, check your hoses, radiator and water pump to see if they’re damaged. If they are, your heater will not be able to work properly. Take your vehicle to the shop if you notice any damage or if the heating problem persists.
- Broken thermostat: Finally, you may have a broken thermostat. Your thermostat is programmed to turn on and off at certain temperatures, and if it can’t accurately sense the temperature, you will experience problems. Check the thermostat gauge after your engine has a chance to warm up. If the indicator remains on “cold,” your heater will not work properly. Take the car to a trusted service shop to check the problem. If it is a broken thermostat, you’ll be relieved to know that it’s a relatively simple fix.
Now that you know which signs to watch out for, you’ll never be surprised by a malfunctioning heater again.
