How long does the fan motor switch last?

Maintaining the right temperature in the car interior is not an easy task. A number of components must work together to keep your car's interior comfortable. The heating and air conditioning systems in your car work to convert the intake air into usable air at the right temperature. The blower motor and blower motor switch are used to fill the vehicle interior with air from the heating or air conditioning systems. You will be able to control the fan speed with the fan motor switch. This switch will only be used when you need to adjust the amount of air entering the vehicle interior.

The blower motor switch is designed to last the life of the vehicle, but rarely. During periods of extreme heat or cold, the fan motor switch is constantly used. The more often a switch is used, the more it inevitably wears out. A broken electric fan switch will greatly reduce your ability to control the temperature inside your vehicle. Considering the signs your vehicle will give when this switch fails, you can avoid long periods without proper heating and air conditioning.

Most car owners don't realize how important this part of their car is until they run into problems. No matter how well your air conditioning system works, without a properly functioning blower switch, you will not be able to achieve the desired comfortable cabin temperature. When the fan switch on your car fails, here are some things you may start to notice:

• Inability to fill the interior of your car with warm or cold air
• The fan switch will start to work erratically
• The fan does not turn on at all
• The fan switch will only work in one position.

Making sure all the components in your car's air conditioning and heating system are working properly is an important part of keeping you comfortable no matter what the weather is like outside. If there are any problems with the heater fan system, have a professional mechanic check and replace the fan motor switch if necessary.
