The heater in your vehicle is something that you probably take for granted. Climate control heat has become more of a standard feature rather than something you could add on. Some of the first few vehicles would have portable heaters. These would include gas lamps or burners that would warm up the interior of the vehicle. They were also the same type of heaters that horse carriages used for centuries. As the development of vehicles improved, so did the heater itself.
In 1937, advanced climate control was used by having filters and you could regulate airflow and temperature. Heater cores were typically used, this was because gas heaters were too costly. In 1939, GM introduced car seat heaters on certain cars. Eventually military vehicles were able to be comfortable for troops who were fighting in the cold weather and temperatures. It was not until the 1960’s when heaters became standard in all the vehicles.
Cadillac vehicles were the first ones to have a fully automatic climate control. This allowed those in the vehicle to adjust the temperature to what they wanted. Since this happened, very little has changed. Cars still use a heater core design, and even the hybrids do. While you may not think of the heater as more than something that is convenient, it also is necessary in the winter months. Doing so will help warm up the vehicle, and improve the visibility when you drive.
Remember to check the heater and defrost of the vehicle that they are operating correctly. Any sign of an issue should mean you bring the vehicle in immediately. Doing so can help keep the vehicle safe and reliable for you during the winter months. Also remember to fully scrape the windshield and rear windshield of the vehicle. The side windows and mirrors will also need to be scraped clear as well.
