There are few things more annoying than jumping into your car on a freezing winter day only to discover that your heater isn't working.
Unfortunately, there are quite a few reasons that could cause this.
If you heater fan isn't blowing it's likely the blower motor has gone out. But it could also be that a switch has gone out. If, however, your fan does blow but only when you're driving at certain speeds, the culprit could be a bad blower resistor. The good news is that the repair is likely not expensive.
If you've got heat but it's just not up to par, you could have a bad thermostat, especially if your dashboard temperature indicator is low. This condition could turn on your "check engine" light.
Another cause of less-than-adequate heat could lie in your car's heater core. If it's blocked it won't heat. A flush can solve the problem. If you hear a clicking sound and no air is blowing from the vents, a blen

This condition can be caused by many things but sometimes it is as simple as a bad thermostat. Take note of the temperature gauge on your dash and if it is runs lower than normal the thermostat is most likely the source of the problem. On many newer cars this could also activate a "check engine" warning light as a car that runs too cool will not get optimal fuel economy. Another cause for poor heat could be a restricted heater core. This is a small radiator-looking core that fits up in the dash. When the fan blows air across it, its heat is blown into the car. If this system becomes plugged up, the coolant can't transmit the heat to the core and it
