  1. Tired of the heat

    2010-2013 Mazda 3 & Skyactiv Discussion
    Hey guys, I have a 2011 Mazda 3. The air conditioning won’t work. Put a jumper in for the ac relay and the compressor kicks on but the coolant fan doesn’t. Even with the compressor running it still blows out hot air. Any suggestions?

    2014-2018 Mazda 3 Skyactiv Appearance & Interior
    I noticed today the heat does not work in my 2015 isport Mazda3. When I turn the knob to heat only cold air comes out. I also noticed when I turn the knob to max ac the knob pops back up when I let go of it. I think there may be something going on behind the knob preventing the heat from...
  3. Airbox heat shield/wrap

    2014-2018 Mazda 3 Skyactiv Engine and Performance
    I was looking at the IAT reading earlier and I got a constant 40 degree on an average sunny day and I do feel the car being more sluggish when that happens. Can’t imagine what it would be like when it’s actually hot out. So now I’m thinking about adding a heat shield/wrapping the oe airbox. I’m...

    2014-2018 Mazda 3 Skyactiv Appearance & Interior
    SO it was pretty hot on Saturday, and well my screen didn't work for a complete 45-60 minute drive. Luckily I was able to park in the shade when I arrived so it worked for the drive home. I have not yet bought a sun shade which would fix this issue, but it seems like this is something Mazda...

    2014-2018 Mazda 3 Skyactiv Discussion
    Was driving the car today and noticed it was getting quite warm in the cabin with the windows down. I always keep the thermostat at 68, A/C Off. But today I look down and it increased by itself to 88 degrees without me touching knobs. It has done this once before, but I thought it was a fluke...
  13. Thankful for good heat

    2014-2018 Mazda 3 Skyactiv Discussion
    I very happy with how fast the 2.5 gets warm and the heat it puts out. We are in the throws of a nasty cold spell in New England. I'm very happy my 3 is toasty every morning. My previous car was a Saturn Astra. It had the best heat of any car I've owned - almost too hot.

  19. replace or just remove exhaust heat shield?

    2004-2009 Mazda 3 Performance & Mods
    Planning on installing the new exhaust in a couple weeks. My heat shield stuff (I'm guessing that's what it is) is falling off and torn on the bottom of the car. Should I replace it when I put in the new exhaust? Or will it make any difference?
