A/C
Mine works great (at times). On long trips over 3 hours, it tends to freeze up and stop blowing air at all. Mazda dealer said they are aware of the problem and replaced some part behind my glove box. It still happens once in a blue moon though, but I have given up on trying to get it fixed cause the dealer says they cant drive my car for 3 hours to get it to do that and I dont want them to anyway.
I am not sure why some people (uclap) and others say do not recirculate. When you look at owners manuals from all auto companies, they say use "fresh" when you first get in the car and then as it cools down, switch to recirculate to get the maximum cooling since it is re-processing the cool air in the car and not working on cooling the hot outside air. But if you are in a rainstorm, use the fresh setting cause the car will fog up with the recirc button on.
