What is the difference between auto and circulate on thermostat?
Auto: The fan will run only when the heating or cooling system is on. Circulate: The fan will run at random intervals at least 35% of the time to keep air circulating throughout your home. Most new thermostats have a “circulate” option that allows you to set the fan to run a certain amount of time per hour.
Why does the blower motor keep running after I Turn Off the car?
Why does the blower motor keep running after I turn off the car? If your car uses a blower motor controller, it can keep running the blower motor after you shut down the engine. Those used to be installed only on vehicles with automatic climate control with variable speed fans, but now they’re installed on many late model vehicles.
What should I do if my blower wont shut off?
If the blower stops with either of these steps, the problem is in the HVAC control module. However, if the blower continues to run at high speed with either of those tests, replace the blower motor control processor. Just as an FYI, the retail price of the blower motor control processor is $280.34.
What are the downsides of a blower motor?
The downside of blower motor resistors is that, in order to reduce voltage, a resistor converts the energy into heat. These days cars can’t afford to waste that energy—there are simply too many electrical accessories to run.
What happens if you lose the blower motor relay?
The blower motor is the component responsible for pushing air through the vents of your vehicle’s heating and air conditioning systems. Without it, the AC system will not be able to circulate any heated or cooled air. The blower motor relay controls the current used to power the blower motor,…

What causes a bad or failing blower motor relay?
Blown fuses. One of the first symptoms of a bad or failing AC blower motor relay is a blown AC blower motor relay circuit fuse. If the blower motor relay develops any sort of problem that hinders its ability to properly limit and distribute power, it may cause the blower motor fuse to blow. Any sort of electrical spikes or excessive current…
