Homemade Air Conditioner with Car Blower Motor

This is my homemade air conditioner. I built this by starting with a regular cooler and then I cut out a styofoam piece for the lid so I didn't have to destroy my cooler. The fan is a AC blower motor from a Toyota Tercel that I picked up from the junkyard for $5. You can run it off of a 12V battery, however I choose to run it from the wall. I did this by taking an old 350W power supply and cutting off the connectors. Then I connected all the orange wires to the positive motor terminal, and the I connected the white wire from the power supply to the negative motor terminal. This combination gives 8.3V, which is enough power for this motor. You can connect the yellow wires to the positive motor terminal and the black wires to the negative motor terminal to get a full 12V. This fan really pulls in a lot of air and is much more effective than a regular desk fan.

If a person used a 12 volt cooler to keep the ice in it wouldn't melt unless it was unplugged.

U cud use DRY ICE

Author BLOODjack143 ( ago)
Lol I made a miniature version of this is by using a laptop fan

Author silentriot evenflow ( ago)
LOL . . . . LOL

Author marryson123 ( ago)
have u tried using dried ice inside your cooler? I wonder if it would work better, because dried ice dont melt.

This is how millionaires are birth American ingenuity!!!

I'd like to know what year the Toyota Terce was that you got the blower motor out of. -thanks

Author 000mrman105 ( ago)
will u make one with a compressor like a real AC

Author batterymaker ( ago)
Okay, it's a swamp cooler. Neat idea!

Author Joy Z ( ago)
that is a great idea :)

Really nice video. Great idea using a blower motor from a vehicle. It's already matched to run on 12v. I'm using videos like yours to make one for my Durango as the A/C is shot. $1200.00 to fix it! What I'm doing a little different is along with frozen 2 liter soda bottles(8) I'm also laying in some metal lathe to act as like a coil to collect the moisture in humid air and let it condense leaving dry cool air to be blown into the vehicle. Thanks again for your ingenuity.

Hello how much will it cool a room? in Celsius ? aprox, thanks !

Author kitisabuebos ( ago)
I liked this idea :)

My opinion, switches are a dime a dozen. He should give it a shot and see if the switch gets warm -.-

Not bad sir. The New Macgyver :D

Author J F ( ago)
you'll be fine, but i guess you figured that out already. You'll also only have "high" setting, or if you want to get really fancy, you can rig up 3 switches, one with a single ballast resistor (chrysler electronic ignition style) in series with the motor, and one with two ballasts, and then one straight from the battery. the 2-ballast will give you low speed, the single medium, and no resistor=high speed. they will also add a good bit of heat to your air, so mount the resistors outside the duct

Well he mentions 100 F and many of the viewers are in those climate zones

Author cyrylthewolf ( ago)
Does this guy SOUND like he's in one of those climates?

Watch the video but don't talk shit like you expect him to assume YOUR environment. Figure out your OWN solution or adapt HIS. Don't ask him stupid questions.


Author guayacan07 ( ago)
Have you heard of different countries and different climate zones? Did you know that some countries ONLY have summer and what they call " winter" is heat with lots of rain?

Author cyrylthewolf ( ago)
365 days? Do YOU run your A/C during the fall? How about the winter?


Author Hostile Giraffe ( ago)
The freezer will continue to be cold wither he is using the ice from it anyway. He is simply using the ice that is already made to further cool his house. Please stop hating, especially considering your not good at it.

Author HKGamming ( ago)
Add sugar to the ice so it doesn't melt as fast

Author suprcustom ( ago)
The funny thing is that if the Freezer you use to make the ice is in the same house as this type of cooler you are actually heating your house not cooling it.

Author jtmax24 ( ago)
That's a lot of power and wiring. But I bet that SOB blows some air.

Author spinergy686 ( ago)
I came across your video & I was hoping you can help me. I cannot find the short in my truck blower wiring. If I run the blower straight from the 12v battery with a toggle switch will I be at risk of fire?

ghetto version

Author david cody ( ago)
hey man this is cool as a mutha i like it alot that was a good idea

Author guayacan07 ( ago)
so you gonna stop every 2 hrs to get a bag of ice? $2 for a bag of ice, 4 a day,$8 a day , in 365 days is $2,920 not worth it

A/C & a place for cold beer.

Author Willie Murphy ( ago)

Author Synthbin ( ago)
Looks nice ! But i wonder can it cool down a normal room? and does the room temperature actually gets lower?

Author origamix72 ( ago)
u can use a high output air compresser if u want

Author RocketBurn11 ( ago)
If you used dry ice would it displace oxygen indoors or would it be too little to matter? Just curious, my dorm doesn't have AC and we can't have AC units so I'm planning to make something like this for next year.

Author bajabilly2004 ( ago)
you should have paid an extra 15$ and bought the whole toyota tercel that fan came out of, chances are that car had ac..

Author animebsd ( ago)
@hutchtransfer hey im building a swamp cooler also! i used a large ice cooler for drinks, beer ,(ect) and cut some holes in it. got a nice blower fan from a slim pedistal fan. and a pump from goodwill thats for a fountain. ive got the blower, pump and wiring done in this thing all im waiting for now is for the pads to arive in the mail

Author brenda pardee ( ago)
does it keep your car cold!

Author mondays89 ( ago)
Great vid! and when the jugs melt down you can just toss them back in the freezer and refreeze them then exchange them for prefrozen jugs. Very good idea!

Author dreamextreme7 ( ago)

Thanks for your detailed feedback and thanx for responding so quickly..

Author dreamextreme7 ( ago)
Is there any reason you couldn't use a regular plug in fan for an apartment room? Does the battery make it safer avoiding electrical problems or something??

Author TheRealTrevorland ( ago)
Neat idea! How long does the ice last?
