Key Features & Benefits

This part basically takes the signal from your blower motor control – usually from a switch on your dash or a climate control system – and boosts it to actually power the blower motor itself. It’s like a little amplifier for the fan. It manages the speed, too – so when you dial up the fan, this stage is what’s sending more power to make it blow harder. It also often includes a resistor network to provide different fan speeds. It's a key part of your heating and air conditioning system, obviously. It sits between the switch you use to control the fan and the blower motor itself. Without this, that switch isn’t going to do anything. It's generally housed within the HVAC box, usually tucked away near the blower motor.

Symptoms, Risks & Replacements

If this part fails, you’ll probably notice it right away. You might find your blower motor only works on high, or doesn’t work at all, or maybe just blows intermittently. Sometimes it can even cause the fuse to blow repeatedly. It acts like a shield, protecting the motor from getting too much voltage. When it goes bad, that protection disappears, and things can get messy. Replacing this is usually a pretty straightforward repair. You can find these parts, and a lot of other HVAC components, over at Fixparts Online if you’re looking. It’s often much cheaper than taking it to a shop.
