The heater core in your car’s HVAC system produces hot air during cold weather to keep your vehicle warm. During summer, the AC and its various components cool the air. The blower motor is responsible for pushing conditioned air both heated and cooled from the dash into the vehicle’s cabin. You may have about three blower motors, each motor with its blower motor switch, depending on the model of your car.
What is the Purpose of Blower Motor Switch?
The blower motor switch essentially allows you to adjust the airflow in your car. It makes you choose between high, medium, low, and off-speed for the fan. The switch wears out over time due to regular wear and tear, and the switch will fail, necessitating the purchase of a new blower motor switch.
Most switches display unpredictable behavior before entirely failing, so you should be able to detect impending failure. Although a malfunctioning blower motor switch will not prohibit you from driving, you must be comfortable in your car, and your windows must be unfogged and clear. Have the issue looked at and fixed as soon as possible.
When is Blower Motor Switch Replacement Needed?
- Fan operates in some switch positions but not others.
