I know, I know, this is common problem. But I’m just wondering, is it possible to fix it. Can anybody here, who has Mazda 3 2005/2006 get cool air from A/C when outside temperature +27C and more. My A/C works well when outside less that +27C. But I need A/C as well when it more that +27C.

Should I try to fix it or it is impossible?

Guys and girls, please help.

Several people have wired a resistor into the thermistor basically tricking it into thinking the temperature is five degrees higher. Since it thinks it's hotter it works longer to cool down. Most also hooked up a timer delay so that it would turn off after a set amount of time to avoid freezing the evaporator.

Beyond that there are a few things you can do.
- tint your windows if you haven't already. If you haven't I recommend ceramic tint as it rejects more heat than metalized.
- get a sun shade for the windshield. Even if the inside of the car still gets hot it helps keep the dash from being superheated
- when you first turn on the car turn the A/C to face only, recirc, on high speed. That way all of the air goes through the ducts in the dash and help cool it down. Plus when the vents are set to head/foot then you're splitting air back to the floor vents for the back seats, which if you're by yourself in the car is kind of wasted air for the initial cool down.

 

Hi guys and girls.
Yesterday evening it was around +30C, so when I drive from work i can handle it so A/C get cool air, but as soon as I stopped on traffic light is blow warm air even I'm on recirc.

I can fill when my compressor on and air blow much colder, but why my compressor off so quickly? Even when I drive my compressor on only for 5-7 second no more, why???

 

It was 91F here today and my air was blowing ice cold.

 

On heavy and medium heavy (3/4 throttle) the compressor turns off, only other thing is that there is a TSB for the computer to be recalibrated concerning the a/c but thats for another reason

 

I've got Mazda 3 2005/2006 and get cool air from A/C when outside temperature +27C and more, I live in California, no problem.
