How does a blower work on an air conditioner?

It takes the cool air created by your air-conditioner and circulates it throughout your indoor space to ensure that the temperature reaches the level dictated by the thermostat. It performs this task by spinning a fan, which causes air to move through the ducts and vents in your home.

Why does my AC Heat fan make a clicking noise?

If your interior AC/ Heat fan (blower motor) is making noise like a card in a bicycle spoke, then you probably just need to clean out the blower motor which is easy and free. Leaves and debris gets in the blower motor and make a clicking noise when the fan hits the leaves.

Why does my HVAC blower need to be replaced?

The blower motor is the part of your HVAC system that uses the most energy, so it may very well be the culprit if you see a significant rise in your utility bills. An aging, problematic, or dirty motor has to work harder to properly circulate conditioned air throughout your home, which leads to higher energy consumption.

How can I tell if my blower motor is faulty?

This is usually the first indication that you may have a faulty blower motor. If the airflow coming out of the vents is weak, it can mean that your blower motor is having a hard time pushing enough air through the ducts to achieve your desired temperature.

Is the 25A fuse good for an A / C blower?

The 25A Heater A/C fuse is probably good IF you have full speed on Max A/C. That’s where the power comes from to kick the relay. The connection into the switch (yellow wire) is good if you have any speed to the blower in any position (vent, heat, a/c). From the switch, three wires run to the resistors under the hood.

What causes a fuse to blow on a blower motor?

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 from a bad relay will blow the fuse and cut power in order to protect the system.

How does an A / C blower work on a corvette?

On Max A/C, internal air is recirculated. On normal, external air is brought in. This is done with a vacuum controled valve on the right side near the passengers foot behind the kick plate. If this isn’t functioning, you might not be getting the recirculation you expect on Max.

What to do if your car AC is not blowing?

Depending on what kind of car you have, it should be a pretty simple fix. The problem sounds like it is with your blower motor, not your AC system. Hopefully, the blower motor simply blew a fuse. Find your fuse panel and check the fuse for the “blower motor” or “vent fan” or something like that.
