- DIY A/C Recharge. This car is a 2007 Mazda 3 with 2.3L engine. The complaint was intermittent a/c light flashing and then shutting off compressor. The a/c was not cooling properly at idle and in traffic. This is how I fixed it. I'm not an expert A/C mechanic but this has worked for me on several vehicles. Good luck.

Purchased: August 2023 - still works GREAT!I ruclips.net/user/postUgkxxsUnXhGsSJLim_XnMHyQK0u3XVaW-CGn live in a studio and during the summer it gets scorching hot - really old building with no ac units. I can’t express how EASY it was to install. This unit has been a life savior during the summer and some days during other seasons where it can still be a bit warm at night. In this small place is my friend, a husky, poodle mix and myself. We need AC - lolI don’t use the dehumidifier option - I’m not sure if it will leak in my house, since I did not install the small draining hose that came with it. May look into it late but I don’t worry about much humidity in the apartment. I don’t understand why the negative reviews since all things mentioned, I personally did not find issues with. Definitely worth it!
*Works so well **Fastly.Cool** that it only requires daytime operation until high temp and humidity are overnight. It is difficult to get to side filters, but back is easily accessible.*
I've had no issues with my AC light. Not that I've noticed anyway. The air blowing when on is only cold when I have 1 interior vent open but when I open 2 vents it's far too warm.
I think my problem is similar to yours. For reassurance I will check my compressor first until then I will hunt for some super tech.
Thanks for the video.
Yes it sounds like a low charge. Supertech is the walmart brand but any compatible brand should work. Good luck.
Thank you I did it. Blessings.
hi great video my gf just bought a 2008 mazda 3 2.3 did a pressure test on the low side port with ac on showed 0 psi with ac on my compressor and clutch are spinning but not cycling no cold air from dash .? can i get your opinion
Congratulations for the explanation of the video, I have a question after the video, any more problems with the AC, any leaks?
No it still works great, thanks.
Excent vid! Thanks. Any suggestion from anyone as to why the freon didn't get sucked into the Low port? The canister shows 100# when I put it on the Low Port nipple. Never changed in 5 minutes of shaking canister?
Make sure the cannister is upside down
it does show some pressure with car turned off but with ac on high 0 psi there is a small pin leak of green by compressor.
Sounds like you're system is empty. If so you will need to get a vacuum pump and fix any leaks before recharging. If you don't have the gauges and vacuum pump it will be cheaper to take it to a shop.
What type of Freon does it use
Mine does same hot air when idle when driving no problem. Ill take a look when summer time hits right now its winter😝. Would winter give you different readings in pressure?
mine had the same issue, turns out i had to get a new thermostat
What was you fix ?
Thanks for the answer, in my case, the car cooled only on the passenger side, on the driver's side only normal air, did that happen to you at some point?
No mine didn't do that, it sounds like you may need to add some freon. Good luck.
Thats happening to me too, did you find out what it was?
Have you find out the problem?
Thank you
You're welcome.
I drive a 2005 Mazda 3 and my a/c is constantly blowing hot air even when idle. The a/c pipes are hot when touched, and I just added freon a month ago. Any suggestions/ideas?
Sorry there are too many possibilities. I'd check the pressure in the system and check the compressor. Good luck.
Have you found any solution? Having the same problem.
Did u ever fix ac
@@joeywitt7129 did you find it out?
@@PlexTheG you find it out ?
my mazda is cold when sitting still on fan speed 2 but as soon as I start to drive or turn it up to 3 or 4 it starts blowing hot air. Any suggestions? Thanks
Sounds like a low charge.
@@TheHandsOnChannel This is my issue as well that I'm looking into. Promising to see you suggest it's a low charge that I can fix myself.
The Hands On Channel wasn’t a low charge! Still dealing with it.
@@MichelHoude Did you ever solve this?
@@SeanSRSo did you ever figure out what the issue was, and how did you fix it?
Fixin' to attempt to Fix it!
hickok45 here
Fr tho 😂
A slightly younger version lol
My buddys a/c makes this horrible squeal (metal on metal sound) at idle and when pressing the brakes. Do you know whats causing that? I thought maybe it was the compressor or condenser but he said hes had them recently changed, within 2 years he said.
I cant think of anything other than the A/C clutch might be failing but it seems like it would make the noise all the time not just at idle. Does the ac still cool when the noise is present? You could try to watch the compressor with your buddy in the car duplicating the symptoms. You might be able to see the clutch slipping or pinpoint the source. Good luck.
The a/c blows hot air, we charged it fully yesterday, still hot air. Clutch isnt slipping we did check for that. When he turns the a/c fully off the squeal stops.
@@oustandingsitter6106 Could it be a belt squeak? If so you may have overcharged the system causing the comp to strain the belt. It could also be a blockage in the orifice tube/screen. This would cause high pressure to build up in the system.
Ah ok, thats probably what it is. Thankyou for your help/time.
@@oustandingsitter6106 You're welcome, good luck.
Ah!!!! Ok...thats why the light started to cut in and out...same thing has been happening to mine...cant complain though....04 car is 20 yrs old and this is the first time this has needed recharging.
Your air should be turned to MAX, not just on. You’re also suppose to close the passenger side air vents
exactly, it should be blowing around 40-45f on MAX FAN speed, hell my 2014 Mazda 3 is showing around 50f on low setting but when I crank it up to max, it's at 77f, which is super high in terms of temp for an AC system even @ 94f outside, it should still be blowing 43ish out of the vent on max speed at idle.
What kind of refrigerant is that?
If memory serves me it was r134. Got it at walmart.
Do you need to put the ac all in high??
Yes max air on high.
@@TheHandsOnChannel oh okay thanks man
If you start the car and idle it, with the AC on, and connect the refill bottle... what does it mean if it pegs the pin in the red zone as soon as you attach it?
It could be a blockage, overcharged or a bad compressor.
I kept runnin into that issue until I forgot I had the bottle attach and turned the car off, and when I came back like 10 mins later from bein kinda frustrated and started the car Nd the gauge started working, so idk if It’s I let the car sit or it was having the bottle connected before starting the car, also i think it only jumped to red when I pulled the trigger so it could just not be pushing the low side valve right and all the pressure from the can is trapped in the sealed space u made by putting the connector on
The can has to be upside down for better flow it’s on the instructions
Mine says rotate from 12 to 3 o'clock and back again.
The Hands On Channel Exactly, with the bottom of the can at 12 and 3.
The Mazda fan switches have 2 separate sets of contacts inside: one that run the vent blower fan; and another set that tells the computer that the switch is on (any fan speed) so that it will turn on the compressor.
The compressor contacts get unreliable over time and the compressor will disengage and the light will turn off. If you turn the switch to any other position and back again it will work until it goes off again. Only permanent fix is to replace the fan switch.
When the compressor contacts start acting up, the vent blower fan continues to work normally.
The reason the AC system did not need very much refrigerant because that wasn't the cause of the light going off. The cooling temp went down, but the light problem will remain.
Okay, thanks. So far it's been good since the recharge, but if it acts up again I will check the switch.
@@TheHandsOnChannel curious if this held up?
@@Rusnakjd Yes it still works great.
how much psi should it have?
So I have the same car and my light for the AC is yellow not green. What’s the difference?
Sorry, IDK. Try looking in some of the Mazda forums. I've found them to be a good source when I get stumped. Good luck!
After 4 years, does it still blow cold?
Yes.
@@TheHandsOnChannel Mine is a 2006 Mazda 3 same engine but I am experiencing driver side warm to hot air and passenger side cooler but not cold enough as I could hear the ac clutch engage. Do you think this would fix the problem?
@@mr2cqql IDK does your car have separate climate control for driver/passenger side?
@The Hands On Channel did it turn out to be just low charge? Mine does the same, it will blow somewhat cooler air out of the passenger center vent and the driver side will be a little warmer, I have my theory for this, is that since the charge is low, and the TXV and entrance for the evap refrigerant is on the passenger side, that part of the evap gets whatever is left in the system and by the time it reaches the driver side vent part of the evap, there isn't enough cold refrigerant to cool the whole evaporator.
Wish he would’ve shown what part it hooks on to. Otherwise it was a waste for me bc I could barely see what the compressor or part looks like.
Can it Run while adding freon?
Yes you want the car running, if that's what you mean.
@@TheHandsOnChannel oh I meant the AC, but thanks for the help
Well maybe if it does when acelerate sound to me like a ford ac problem.
Really he’s watching it? I sure wish I could. Took him forever to get his life together
My a/c stopped working in my 2008 mazda3 last summer so I took it in and they said I needed a new compressor which cost me $800 (installation included) but the a/c still never really got cold, more like Luke warm so I've been going without air since then and its been like riding around in a coffin. I don't really know what to do. I don't know if I got a faulty compressor or what. I should have taken the car right back to the shop last summer when I knew almost right away it wasn't working right, but I didn't, I've just been suffering in the heat all last summer and this one. I just don't know what the problem is. I hate to fork out another $800 for another new compressor and it still not work. I don't have money to guestimate at this part and that part finding the problem. Does anyone have any advice?
I'm so upset about this because other than the a/c problem its been a great car. But what sucks is the cars not paid for and its a BLACK car with BLACK leather interior and I smolder in it all summer long. I still have another 27 car payments to go on it. I don't have extra money laying around to buy a dozen different parts that "MIGHT" be the cause of the a/c not working so I'm probably gonna sweat it out til its paid off and then sell it in the winter and then the a/c can be their problem to fix. I want an old mini-van without payments. I'll sell my Mazda and go buy an older mini-van out right with ice cold air and have no more damn car payments, those suck! And those damn dealerships financially rape your ass and sell you a $2,500 car for $7,000. Assholes!
I'd try to take it back to the shop that worked on it last and see if they will work with you. I think if you explain the situation they should be able to charge it properly and diagnose for a hundred or so. If they wont help you never use them again. Unfortunately that's about all we can do these days.
Did you sell it? What year is it?
The exact same thing happened to me.. Needed a new compressor (2005 Mazda 3) and I was thinking it would improve my AC... nope-- it was putting out lukewarm air and now (months later) it's putting out hot air. I'm taking it in tomorrow to get freon in it.. hope it works.
@@moxie5915 I can give you troubleshooting or some advise about that compressor if you like because adding freon wont help You.
You should be turning the bottle upside down... as it is a liquid under pressure
NO! never recharge a car with the can upside down, the fill port is often way too close to the compressor and you can slug it with it in a liquid state if it doesn't have time to revert to gas before hitting the compressor and ruin it. Although these cases are super rare, it's always better safe than sorry.
Not for nothing, engine bays retain more heat when they are covered in filth like this one. Detail and degrease you’re engine bays no matter what car you have. You will actually be helping every component under the hood last longer and run better... even the AC!
Come on Rhyno, the engine in the video wasn't filthy. It's a bit dusty but this car drives on gravel roads. That's the reality of living in the country. I clean it every time I change the oil. I do agree that you don't want a grease ball around your engine but some dust wont hurt a thing (especially the AC's ability to cool). Thanks for the comment though.
It was just meant as a tip to keep the engine bay clean for anyone who read my comment. Not enough people do it and it causes premature failure on a lot of components under the hood. My statement had nothing to do with your AC being charged.
@@rhyno811 My bad, I had kinda a rough couple of days and probably just took it wrong. Sorry and thanks for the comment.
4-cylinder or 6-cylinder, lol
2.3 L 4 cyl. its in the description.
There is no 6 cylinder

The compressor should stay on an a Mazda 3 .
No it shouldn't actually. My 2014 3, before running low, cycled on and off with the condenser fan turning on and off with it, if it's low it will constantly stay on as mine currently does. It's just the way newer cars work. It turns on and off with the Evaporator temperature sensor, and if your evaporator can never get down to the temperature required for this whole operation to take place, it will just constantly stay on as it senses it's not at the optimal temperature yet.
THIS GUY IS NOT EVEN SHOWING WHERE THE COMPRESER IS AT AND HE'S NOT EXPLAINING THINGS LIKE LETTING THE HOT AIR OUT NOTHING! THAT'S NOT HOW YOU DO A " HOW TO" VIDEO.
