Sounds about right. They have branded you as a nuisance and cut you off. Next the dealers will tell you to go somewhere else. A friend went through the same BS with Chrysler as he was trying to resolve a problem. Mazda doesn't care,they kep selling these cars on looks etc. and nothing more. A 20 year old doesn't give a rats ass about the A/C as long as he looks good and the car goes fast.
Today it was 70F in the sun and my A/Cs coldest temp out of the vent was 43 to 44F. But at a outside temp of 80F plus I don't think the A/C will be a big help.

Although I have had major issue with the weak AC mine has been doing OK - temps are in the mid 80's -
Last summer (about the same temps) I would run the fan on 3 - recirculate on - all the time and the car was never really cool - the last few days I have been using fan speed 3 at first - then switch back and forth between 2 & 3 - 3 is a little cold (something I thought I would never say) and 2 is a little warm. Some of the time I turn it to outside air and leave the fan on 3 - it still seems to keep the car cool. This is a new condition - I am 100% sure something has changed for the better.
When I shut the car off - the radiator fan keeps running for a few seconds - my car did not do this before - My assumption is the fan must be running more than it did before - although I can not tell if it is running while I am driving - or if it did before.
The radiator fan pulls air through the condensor - which does have an impact on the ability of the AC system to produce cold air. I do not know why the radiator fan started doing this - as far as I know Mazda did not change anything on my car - or at least they did not indicate it on my invoice.
I also noticed that when I turn my AC on - the radiator fan almost always starts up right away - this is also something new - it did not do this last year.
Maybe this has something to do with the problem - I do not know -
If anyone is having weak AC issues - does your radiator fan start up as soon as you turn on the AC?
Does it continue to run after you shut the car off?
It is normal for the Radiator fan to come on with the AC

Ha that is EXACTLY where mine is making the sound...my Mazda dealer replaced my seat belt unit and scratched the bejesus out of the inside of my car while either taking the seat out or replacing it...and the funniest and absolutely most frustrating thing is that like 2 days later what happens...the darn clicking is back with avengence!!!

Hey I have a question...I just got my '06 Mazda 3 back from the dealership. They replaced my whole audio unit due to the clock not keeping proper time. My question is what is supposed to light up...it just doesn't quite look the same. I know that the area around the volume button is illuminated, as well as the 2 dials for the heat/ac and the direction, but what else should be? Or am I just going crazy?

I think you nailed it when you said that the difference between the previous Mazdas w/climate control are the extra sensors.
Yeah, I meant refridgerant when I said coolant. The former takes too long to type.
Like z71bill wrote : The Mazda3 system is set up a little different - it also has a temperature sensor in front of the evaperator - it shuts the compressor down based on the evaperator hitting a set temperature. The Mazda has 2 sensors and it could be how they are programmed or designed that is affecting the compressor cycle, even though it shouldn't.
From the A/C link I posted: "There is a high pressure switch, a low pressure switch, and a "medium pressure switch. The PCM gets data from all 3 switches, and controls the compressor relay. This is a TXV system, and evaporator icing is controlled by a thermistor on the evap face.
Hard to say if the cycling is caused by hitting the HPCO, another pressure switch, or the anti-icing thermistor. Pressures will tell us plenty. "
I believe the fault lies in the sensors and programming, but only pressure testing the A/C system will help us.
We need to post high and low pressures whatever the ambient, especialy if the same thing happens when it's hot and or cold . But most important, pressures when it's doing it's cycling will tell us much more than you think.
"Someone need to report the system pressures while running the engine at 3,000 rpm it will help us tell you what the system is doing. The description of cycling regardless of ambient sounds like a PCM problem. Post up some 3k rpm test data please."
#3195 of 4993 Update: 2006 Mazda3 GT w/Climate Control A/C
Apr 19, 2006 (11:42 pm)
I keep on running into posts in other forums by 06 Mazda3 owners (GT) models that are claiming that their 3 has great A/C. Again, something is different between ours (2005,2004's) and theirs.
If anyone has any connections to find out what, that would help. Thanks

Pretty much everything on the dash should light up - if it's a button it's lit on mine...

>It is normal for the Radiator fan to come on with the AC
Can't speak specifically about your Mazda (I'm on this board researching a future purchase) but on every car I've had with AC the radiator fan was essentially hard wired to the AC switch. Some of them left it running with the engine off.

Thanks so much for your reply...mine isn't working properly...yet another thing to bring back to my dealership...I haven't had much wrong thank goodness, it's just that anything they touch they mess up.
Thanks again, much appreciated.
