The invention of car heaters
began with the discovery that the heat produced by the automobile's engine could be used to warm up the interior. They became standard equipment for luxury cars and later came to be available for most other cars. As the economy began to slump in the 1920s, many people found themselves in need of additional heat, and car heaters quickly became an essential accessory. Listed below are two ways to keep warm in your car, and the history behind their development.
A motor-driven fan blows warm air from the engine bay to the interior. This system is relatively easy to operate, and there are few issues. However, in rare cases, something can go wrong with the fan. In such cases, a faulty electrical circuit is usually to blame. This circuit is comprised of an on/off switch and a feed wire that runs from the fusebox to the heater motor. Because the heater motor is earthed to the body, a broken circuit can result in the unit not working.
The heating system is most likely malfunctioning when the coolant level is low. To determine if your coolant level is low, take the radiator cap off while the engine is cooled. You can then see how much coolant is left in the tank. If this is the case, top it up using a 50/50 mixture of distilled water and anti-freeze. Remember to never overfill your radiator! To test the heating system's output, set the heater
