Key Features & Benefits

This little guy basically controls your heater and air conditioning fan. It’s how you get air blowing through the vents – everything from a gentle breeze to full blast. It manages the fan speed, and sometimes even directs where the air goes – like defrosting the windshield or sending it to your feet. It takes the signal from your temperature controls and tells the blower motor how to run. Think of it as the brain telling the fan what to do. It sits between the switch you use to control the fan speed and the blower motor itself. It receives power, receives the signal from your climate control panel – you turning the dial for hotter, colder, faster, slower – and then uses that information to send the right amount of electricity to the blower motor. It can also handle things like automatically adjusting the fan speed when you select defrost.

Symptoms, Risks & Replacements

If this module fails, you’ll likely have no air blowing at all, or it might only work on the highest speed. You’ll notice if it’s gone bad, because you’ll be stuck with no heat in the winter or no AC in the summer. Sometimes it’ll start intermittently, working sometimes and not others. It’s one of those things you really appreciate when it is working correctly. You can find these pretty easily, places like Fixparts Online carry a good selection. Replacing it usually isn’t too difficult, but it does depend on your vehicle's make and model, so you might want to look up a guide specific to your car.
