Keeping the cabin of a car at the right temperature is no easy job. A number of components have to work together in order for your car’s cabin to stay comfortable. The heating and A/C systems in your car work to convert the air that is taken in into usable air that is the right temperature. The blower motor and blower motor switch are used to fill the cabin of the car with the air coming from the heating or A/C systems. You will be able to control the speed of the fan by using the blower motor switch. This switch will only be used when you need to adjust the strength of the air that is coming into the cabin of the vehicle.
The blower motor switch is intended to last the life of the vehicle, but rarely does. During periods of extreme warmth or cold, the blower motor switch is constantly in use. The more that the switch is used, the more wear it will inevitably have. Having a broken blower motor switch will severely diminish your ability to control the temperature in the cabin of your vehicle. Taking notice of the signs that your car will give when this switch is going out can help you to avoid long periods without proper heating and A/C.
Most car owners neglect to realize just how important this part of their vehicle is until they begin to experience issues with it. Regardless of how well your air conditioner system is working, without a properly working blower switch you will not be able to get the comfortable cabin temperature you desire. When the blower switch on your car is going out, here are some of the things you may start to notice:
- The inability to fill the cabin of your car with warm or cold air
- The blower switch will begin to operate erratically
- The blower will not come on at all
- The blower switch will only work on one setting
Making sure that all of the components of your car’s A/C and heating system are working properly is an essential part of staying comfortable regardless of what the weather outside is. If any problems emerge with your heater blower system, have a professional mechanic investigate and replace the blower motor switch if required.
