Car Heater Not Working? Here’s Why
People don’t turn on their car heaters until it gets chilly. One of the most frustrating feelings is when you turn on your car heating system during frigid temperatures, and nothing happens. A car heater is designed to warm the passengers inside a car during cold weather. This is achieved by using heat that is produced during the normal operation of the engine, which results in the coolant to heat up. So, if your car’s heating system is not working properly, or not working at all, it can be due to a number of reasons.
The good news is that the heating technology of a car is very simple. The bad news is, there are many reasons for a car’s heating system to stop working. While some of the reasons your car’s heater might stop working are easy fixes, others will require you to make a trip to your local auto repair shop, since only a car mechanic will be able to solve the problem.
If your heater is blowing cold, you might be staring at a plugged heater core or a heater that’s low of coolant. But, if a heater does not work at all, it could be an indicator of a bad switch or blower. In either scenario, there’s not much you can do about it but contact a car mechanic to schedule a maintenance and get radiator service.
When this happens, it is important to remember that most car heaters that run on water cooled engines also use very hot coolant to warm up the interior of the car. This is done by pumping the coolant through the heating core which is similar to a radiator. Once the blower motor forces air out of the heater core, the air passes into the cabin of the car and warms up the interior. So, if you notice cold air being pushed out of the vents, you may have one or more of the following problems:
· Low level of coolant
· A tuck blend door
· A blockage in the heater core
· A bad switch
· A bad linkage
· A heater valve that’s stuck
Any one of these reasons can warrant a radiator service from a professional car mechanic.
Another way a car heater malfunctions is when it stops blowing air at all. This is mostly due to a faulty blower motor, but it can also be due to a number of other reasons. You can grab some diagnostic tools to find out the reason yourself or you can contact a professional car mechanic such as SaspOnline, located in Gainesville, Florida, and schedule a maintenance.
During cold weather, people are used to switch the heating on as soon as they turn the key. So, it pays to get your radiator serviced while you get your AC repaired and schedule a maintenance.
