Where is the fan blower motor on my AC?

All fuses good all relays good. The fan blower for your ac/heater is located under the glovebox. Take your hand and smack the fan blower motor a few times. That’s all it took for for mine to start working again. It’s been working for over 6 month’s now!

Why does my AC fan keep turning off?

First off some background info to get you in the right mode. The speed control chooses the speed of the motor by changing the resistance in series with the DC fan motor. These resistors are all attached to one board with shovel plug attachments and the whole assembly is stuck in the air vent to keel them cool.

How does the speed control on an AC fan work?

The speed control chooses the speed of the motor by changing the resistance in series with the DC fan motor. These resistors are all attached to one board with shovel plug attachments and the whole assembly is stuck in the air vent to keel them cool. The motor drives the air to cook its own resistors.

What makes a car blower fan turn slower?

When the motor is switched onto the lower speeds the electrical power is routed through a series of resistors or a solid state assembly that drops the voltage down to 6 volts, 8 volts and then 10 volts (low, medium low, medium) which in turn makes the blower motor turn slower.

When to change the fan on a Honda Civic?

If your civic fan is broken or makes crazy noise when its on here is part two of how to check or change your civic fan. There can be leaves making noise or a… If your civic fan is broken or makes crazy noise when its on here is part two of how to check or change your civic fan.

Why is my Honda AC fan not working?

As in prove that somehow they shorted something out – as if. After a month without a car (too cold outside to work on it) and much online searching, testing of fuses, resistors etc etc a Honda mechanic my grandson knew suggested to him that it most likely was the whole heating unit that was blown.

Why is my AC not blowing air through the vents?

The ac/heat worked great until a couple days ago. I noticed the fan was not blowing any air through the vents. Then all of a sudden it started blowing full blast, while the recirc, ac, rear defrost button lights all came on and were flashing…then it all turned off.

What happens if you have a bad blower motor?

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.

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…

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.

What’s the problem with my Honda Civic a / C?

2006 Honda Civic. The A/C works for the first 5 minutes of the day (blows pretty cold), then doesn’t come on again. When the A/C works for that first five minutes, the clutch engages (no weird sounds) and the cooling fan is on.

Why does my Honda A / C only work intermittently?

It will work intermittently but after a time will open up. Best test for this is to run it until it stops then check continuity across the clutch coil. Controlers can go bad as well, but typically on this model i have found it is the clutch coil.

How does a 3 speed blower motor work?

Older style blower motor resistor with exposed resistor elements. The blower motor resistor is what’s responsible for giving you three blower speeds. The resistor block contains three different high resistance coils. Think of these coils like a filament in a light bulb.

Why does my blower only work on high speed?

If your blower only operates on its highest speed, chances are you have the series type of blower motor resistor. This is the most common failure mode. To repair the problem, simply replace the resistor block.

Is there a problem with my blower motor?

When the Blower Motor does work, it works great. Can’t seem to put a finger on this problem. Hopefully someone has the answer! Patiently sweating it out while waiting..

Where is the blower motor on a Dodge van?

Will either replace it or, in the interim, will have to grease the shaft of the motor. The blower motor on a 1999 Dodge Ram VAN 1500 is located (when facing the front of the vehicle) below the AC/Heater Core box on the left side) along with the Blower Motor Resistor mounted into the side of that box.

Why does my AC fan keep cutting out?

Starts and stops itself. if your blower is working but keeps cutting out then there are more chances of a faulty blower. I have experienced this with a Q7 fan blower. As the brushes can’t be changed EASILY, this is the best solution in my views.

What can I do if my AC Fan is not working?

You can pull the drawer down by carefully dislodging the stop clips found at the upper edge of the drawer on either side. Squeeze the top sides in a bit to allow the compartment to swing out and down to reveal the wiring behind. Now the resistor board part is fastened to the air vent with two Philips screws.

When do you Know Your AC fan motor is bad?

If the compressor is working but the fan blades are not spinning, the motor is faulty. That’s your cue to turn the system off and call the pros to repair the AC fan motor. Replacing an HVAC motor is a job that can be done quickly once the problem is identified.

Why does my Ford blower fan not work?

Worked perfect for about 8 months. The third time in the shop, the mechanic wired the blower directly to the battery and it worked fine so he knew it wasn’t the blower motor. He checked electrical continuity through the dash and said it was okay. He thought there could be a loose ground wire along the main branch of wires???

Why does my AC fan stop blowing cold air?

Because the fan motor is one of the hardest working parts on an air conditioner, it is subjected to a lot of wear and tear that can lead to frequent repairs or replacement. Once the fan motor breaks down, the AC will stop blowing cold air and that’s something you don’t want on a hot summer’s day.

What are the symptoms of a worn out blower motor?

One of the symptoms of a worn out blower motor is that it can intermittently produce a loud screeching noise when running. How to test a blower motor? If the blower motor doesn’t work at all, the blower motor itself must be tested first. Typically it’s done by measuring the voltage at the blower motor connector when it’s turned on.

What should I do if my car blower won’t work?

The next time the blower motor doesn’t operate, reach under the passenger side dash and tap on the blower motor with the handle of a screwdriver. If the blower starts working the blower motor requires replacement. The car is a 2007 Corolla.

Why does my AC blower motor work intermittently?

Intermittent electrical problems can make you feel like your a blind man trying to catch a stray dog. You can’t post conmments that contain an email address.

How long does it take for a Ford blower fan to work?

Next time, the mechanic again replaced the blower motor again and reportedly tightened the electrical connection. Worked perfect for about 8 months. The third time in the shop, the mechanic wired the blower directly to the battery and it worked fine so he knew it wasn’t the blower motor.
