Ha ha, KBRAIN, you know me, I'm all over this like a donkey on a waffle
So here goes...
I attribute it to the 1 (one, un, uno) radiator fan.
That ONE fan is fine, Mazda would have checked that during design specs stage, trust me, you're the first in a long time around here to have stated the A/C is bad due to a single fan.
My other vehicle has 2 fans and the a/c is always cold. And it's 10 years old!
I'll say it again, ALL CARS are not the same, all cars are like people, even two cars that come off the factory line just seconds apart ARE NOT THE SAME, it's strange to think that, but cars are not SOLID STATE items.
Now, having said that, there are 1,283 different things that could be wrong with YOUR SPECIFIC car, it's WAY TO HARD to try and diagnose over the internet YOUR VEHICLE without having it in front of us.
I wonder if there's a way to install a second one?
Go for it, if you've got the TIME and the MONEY to do it, and want to invest in something that is not guaranteed to work.
I checked the charge this weekend and it is acceptable (97* ambient, 750rpm , LOW-50psi, HIGH-240psi). Couldn't check at 1500rpm because of the lack of throttle cable or assistant.
One
assistant coming up:
Put that on the gas peddle as needed to get the RPM you need.
Next will be the cabin filter, but I don't see how that could possibly affect it unless the airflow is seriously restricted, which it isn't.
CORRECT! (bowdown)
Since I read your message, I have taking more notice of my 06 M5 and also notice the air temperature varies a lot between driving and while at idle.
Again, each car is unique, what is one thing for YOU is not necessarily the cause for another.
If I am driving on the freeway there is no problem. But if I exit the freeway and comes to a stop at a red light while the AC is on I noticed that the air temperature increases to the point where its like the the AC is not on.
Ummmm, hate to tell ya Dave, but that IS the
level of FREON in the reserve tank and what you describe is pressure built up enough gets the freon flowing, ....YES you CAN have the correct PRESSURE, but not enough FREON.
Once I start moving the air temperature goes back down. I do not think this is a problem with the freon charge, but either related to the drive belt or compressor.
Either way, you need to have your A/C serviced.
Dave - The compressor strength can be checked with a set of gauges. Mine checks out healthy, so that doesn't explain it.
Oh dear, again, PRESSURE does not EQUAL amount of FREON, in the system and in the reserve tank. You need to get it serviced.
The drive belt can only be a culprit if it's slipping, or altogether broken.
Yes, and HOLY HELL, broken?!, a broken belt means something is wrong, either a crappy belt to begin with or you did something major wrong, these cars are not old enough to have belts 'break' under normal conditions.
If it's slipping, you'd know it by an awful squeal. I suspect my cause is the 100+ degree weather and the airflow across the condenser.
YES, that is correct! (bowdown)
We always recirculate when running the a/c.
Good, that is correct thing to do.
Please go have your A/C serviced, it will be a lot better once done and you can tell the shop you take it to:
1. You want a report, what did it read before and after.
2. How much FREON did they add?
3. Air temps at the vent BEFORE and AFTER.
Let them know you're going to take it for a test drive for 15 min and come back either WITH improvements or WITHOUT improvements.
lastly, like I said cars are unique, not one car is the same as the other.
...there are other factors, one I've PERSONNALY had happen to me about A/C over the last 28 years....
a) water in the vent system, don't ask, long story.
b) Line leak, slowly about 4% per week, by summer's end, let's just say... the car was blowing hot air again.
c) Parked in shade or sunlight all day, (I know not your case, but still and another long story, but made short, ALL THE BLACK DASHBOARD has to cool before YOU get cool).
d) FREON LOW, after I just had it serviced ! The guy fought me for over an hour, then he said, "Ops, sorry" after I begged and BET HIM MONEY I was right, .... GOT 20% off the bill for my TIME WASTED and being right!
e) Bad compressor, dam thing had DIRT in the system and it clogged the dam compressor AND the A/C condenser lines. (DOH!)
f) Condenser leak, got it back from the dealer after I took it to them after an accident I had, (Snow, fence, front end, NOT GOOD) and well I got home, shut the car off and I hear this faint hisss sound,... well dah, leaking from the SAME Condenser that was in the wreck. !!! Gurrrr!
I could go on and on...
end is... get it serviced, it's not the single FAN.
Peace!(rei)
