Awesome! Great to hear it helped.
 
My A/C has been working great ever since I jiggled the wires, and I'm never going back under my dash as long as things are working. One wrong touch of a wire could screw up the A/C again.

09 Mazda6 S Grand Touring 3.7L
 
Just got the car 1 week ago, & already I need to find what is causing the following. I only have 2 months of factory b-b warranty, and I want to make sure the issue is addressed properly....especially if expensive factory parts are involved! Im thinking this is happening to others:
 
Symptoms:
 
* after 4 hours of drive time, with AC at maximum blower velocity and minimum temperature and NOT on “Auto”.
 
* AC Blower velocity significant reduced.....especially in drivers side.
* AC temperature not even “cool”
* pulled over opened hood while engine running and AC still on.
* The refrigerant line, leading into firewall, was frosted over.
* turned AC off and waited 5 minutes.
* investigated evaporator area under dash
* Water was pouring out of Evap Box, and down onto the floor boards. ( no drain hose? )
* Water was running out onto unidentified electronic control module and wire harness!
* No Protective Loom or Jacket on wire harness either...... 8 \
* Water came into contact with Heater Core OR “High Side (hot side) AC line”, then dripped on passengers feet, burning them.
* water droplets were spitting out of passenger-center vent.
* Next day AC "seems to work"
 
Have only seen mentions of "cooling fan problems" on this car. Could this be the issue? I was driving Highway speeds the whole time....so never say engine temp go up.
Can this cause the refrigerant line to frost over?
 
Someone please point me to another post if it rings a bell.
 
Im trying to avoid being placated with jive nonsense, or worse, for <60 days, when I will fully own the "real" problem with this car. Thank you in advance!

Your system is low on refrigerant. Could be due to many reasons. You need to recharge the system and check for leaks. Read your warrenty to see what is covered, don't just quote b-b warrenty.

Thanks, but I think I found the issue.
 
I found the cabin filter last night (first car Ive had with one) and it was caked with yard debris. The "grating/screen" for recirculation is large....like a chain link fence. I even found a leaf the size of a 50 cent piece. Im 95% this is the problem, because it would certainly explain the frosting and excessive water after thawing. I would think the drain line could be more effectivie though....water running out of the box and onto the floor? Perhaps it was condensing on the outside of the plastic housing? Hmmm..
 
I just need to take it for a long drive on a hot day.
 
I will report any developments for the benefit of others.

I do not know whether this is directly relevant to Mazda6 or not, but for Mazda3 there was a TSB for AC freezing over and starting to blow warm air after driving for extended periods of time at highway speeds with AC on and fan on low. I do not know what the resolution of that was, and my car has done this once, but if anything, the best remedy for future situations like that would be to crank up the fan a bit.

hmm....thats interesting.
 
I will need to investigate that.
 
Thanks!
 
Anyone have a Mazda3 TSB list?

I have a 2010 Mazda 6 with a similar problem. After a few hours the aircon stops blowing cold air. You can hear the fan working, but less air comes out and its not all that cold. If you stop the vehicle for 10 minutes and restart - there is no change. But if you leave it for an hour or two, it works just fine again. What I believe is happening is that something in the air con is freezing up occasionally. Mazda seem unable to fix it. They tried (at least that's what they said) - but I think its a design flaw. Its an intermittent issue and luckily does not happen all that often. Good luck
