  1. Weak A/C

    2019+ Mazda 3 Discussion
    My new 2019 Mazda 3 Sedan has the weakest air-conditioning of any car that I’ve owned in recent memory. I’m taking it into the dealer tomorrow to have it checked. I hope it’s just low on refrigerant and if it is I hope there’s no leaks in the system. I really don’t want some BS answer about it...
  2. A/C leaking on front passenger carpet

    2014-2018 Mazda 3 Skyactiv Discussion
    Just noticed this today. It is definitely related to the A/C as it hasn't rained recently and the water is fresh just after I drove the car for an hour with the A/C on. Everything I look at online is to clear the A/C drain under the car with compressed air, which I will do as soon as I can...
  3. A/c not cooling and bogging motor down

    2004-2009 Mazda3 Discussion
    My 05 a few weeks ago when the a/c or defroster cuts in the car loses power it’s a 5 speed but when you shit at first there is no power then suddenly it kicks in, does this also with the defroster on. The ac has not been working it blows cool for about a minute then gets warm. Anybody seen this...
  4. A/C Compressor Leak

    2010-2013 Mazda 3 Engine and Performance
    Put on a new a/c compressor last weekend, then vacuumed and recharged it to right amount of r134 on Monday. Was about to drive home when I noticed my car smelling like refrigerant. Turns out it was a bad pressure release valve. Is it possible to just replace that valve or I am going to have to...
  5. Take contol of your A/C

    2004-2009 Mazda 3 Performance & Mods
    So this is something very similar to what I did with my 2002 Protege5. Our 2004 to 2009 Mazda 3's manual HVAC system is very similar. Our vent selector is indicating the floor and windshield, or the windshield vent, the A/C system is switch on. The big butt, is that the A/C light fails to...
  6. A/C Vaccun and Recharge

    2010-2013 Mazda 3 & Skyactiv How-To Guides
    Hello all, new to the forums and this is my first question. I have a 2010 Mazda 3 hatchback with the 2.5 AT. Regarding the AC system, today I went out to the check the pressure because my air felt a bit warm. It wasn’t low on pressure, but the Shrader valve wouldn’t shut properly when I...
  7. High side A/C Pressure switch

    2004-2009 Mazda3 Discussion
    Hi everyone, owner of a 2008 Mazda 3i. 2 years ago I had the a/c compressor replaced, and worked fine for nearly 19 months. It now exhibits all symptoms associated with failing/ failed high pressure switch. My questions are: 1. Is there a way to test said switch 2. What's the difficulty in...
  8. Dayton RS-100-4 in A/C vents

    I have completed this installation today, I really like it, specially for the sound. Sent from my Moto G (4) using Tapatalk
  9. Custom "Economy" and "Economy+" A/C Setting?

    2014-2018 Mazda 3 Skyactiv Audio & Electronics
    In my quest for increased fuel economy, I've come up with an idea that I wanted to run by you guys... "Economy" and "Economy+" settings for your air conditioner: - Economy mode would only operate the compressor when the throttle input is at 0% for 5 seconds, regardless of whether or not you...
  10. A/C Duct Cleaning

    2014-2018 Mazda 3 Skyactiv Discussion
    So I'm trying to use the AC Pro Vent and Duct Cleaner and it says to spray the cleaner into the fresh air intake for the AC. Where exactly is that on a 2014 Mazda3? Pics would also be helpful.
  11. Strange issue with a/c

    2010-2013 Mazda 3 & Skyactiv Appearance & Interior
    Please forgive me, I don't know too much about cars honestly. I have a 2010 Mazda 3, it's automatic but it's a very basic model otherwise. Occasionally, the a/c or possibly the fan won't blow at full power even at the highest setting. What is even stranger about this is that about 20-40...
  12. Turning off A/C before turning off car.

    2014-2018 Mazda 3 Skyactiv Discussion
    So my parents keep insisting that if I have A/C on, drive it, then turn the car off without turning the A/C off, I'm going to "Blow the compressor". I'm a little sketchy on this whole idea. Is there are truth to it at all? I drive a 2014 Mazda3 Sport btw.
  13. Rubber-y smell when A/C is on.

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    My csr (2015 GT Mazda3) is letting some weird odor when the A/C is on. It smells like letting a tire inside of your car for the entire day with the windows up. Its that smell like rubber, but comes from the vents. It has 72,000 miles on it. Enviado desde mi SM-N920T mediante Tapatalk
  14. Be careful with your A/C

    2014-2018 Mazda 3 Skyactiv Discussion
    So I bought my 2014 Mazda3 about 4 months ago. It only had 9,000 miles so I thought it was a fantastic deal considering the mileage. About a month after I had it the A/C was making a high-pitched/whirring sound and it wasn't cooling quite as well as I remembered when I first got it. I took it to...

  16. What Does A/C Eco Actually Do?

    2014-2018 Mazda 3 Skyactiv Discussion
    My car has the dual zone climate control system. There are two air conditioning modes - A/C & A/C Eco. The manual says "A/C ECO function is designed to economise use of the air conditioning system. “ A/C ECO ” is displayed to indicate that the air conditioning system is operating at optimum...
  17. A/C Refresher Service

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    The dealership wants $119 for this service. This is something I can do myself, right? I believe it's just a Freon or something of that sort with the added benefit of killing mold and keeping the car smelling new (as they put it)
  18. Climate Control - fan blows cold when A/C is off

    2014-2018 Mazda 3 Skyactiv Discussion
    So, I like to have fresh air slightly circulating in my cars and usually have the fan set at 1, the mode to defrost/floor, and the temperatures to 71/71. I never touch it and leave it like that. It was set like this in my Mazda6 without issue. But with the Mazda3, the fan blows cold air to the...
  19. A/C light comes on when heat turned up

    2004-2009 Mazda3 Discussion
    This particular phenomenon has been occurring during the last couple of days only and I'm unable to pinpoint what caused it. 2007 Mazda 3s Hatch When I have the fan on to blow air in the cabin and the A/C button and light is off, when I turn the heat knob towards heat, the A/C light comes on...
  20. Mazda 3 2011 A/C troubleshooting

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hey all, New to the forum. Trust me, I looked through previous posts to see if I could find something that resembles my problem, but if there is a post about it thats similar to mine, I don't know what search terms to use. I noticed today that my car has weak air pressure coming from the air...
