#4147 of 4991 Mazda3 AC and Gas Mileage
Jan 09, 2008 (7:33 am)
HERE ARE THE FACTS.... If all of you want to keep on beating this up that's OK too....
I have a 2005 Mazda 3 S 2.3 sedan, NO climate control.
Any time you turn your MODE dial to feet or windshield your AC compressor will turn on. Hence reducing your gas mileage.............
I have confirmed this with a Mazda engineer in California and a my Mazda mechanic. This is the way it was designed, it does make sence to me. My honda's do not do that....

I appologized in another message for not understanding what you had written, the fact remains that my 2007 (canadian model) 3 gs sport, manual A/C does not automatically turn the air on in any position that does not have defrost (air to the windshield) on it ie. defrost and mixed (air to the floor and air to the winshield). In pure floor, floor and dash vents (face) and just dash vents (face) the air conditioniing does not come on unless I turn it on, and in no position does it turn on the a/c button and the rec button regardless of temp position as another poster mentioned (I tried it this morning), so I am going to have to toss this one to differences in programming for the different markets (us and canada) though I agree with you if your a/c does act in this way (a/c auto on an floor only) it makes absolutely no sense at all, and is something that should be corrected.
Again sorry for any misunderstanding.

When I was a kid we had a VW Bug. The heat ducts that ran from the engine in the back rusted through from winter road salt. Talk about NO climate control.

Honda now do the same thing has almost all other make. The reason why? Warm temperature from the floor will result in condensation. Using a/c lowers humidity rate so therefore keep the windows from frosting or condensating.

My Honda is a few years old and it does turn on the compressor unless it's on the windshield setting.
What your saying makes sense, but what a waste of gas..... I don't always need dry air in the car......
#4153 of 4991 how to save fuel consumption
Jan 10, 2008 (6:54 am)
You're wright, it cost more fuel. To save some fuel when I'm on the highway I just turn the fan off. The a/c turns off at the same time. At the highway speed theres anough air flow to keep the windows from condensating...at least in the front!

I think the problem with turning the fan off when you have an A/C equipped car is potential growth of mold. I always have the fan running at the minimum speed for that reason.

I'm preaty new to the forum, but I've found your info very handy. I'm a disable vet and normally have to pay someone to do any type of work, because I don't have the right tools, time or my illness won't allowed me. Thank you for sharing this info. I'm in the process of preparing my 04 Mazda 3 H/B for car shows and this manual has come very handy.
Do you know, where could I find the entire engine bay hoses diameters. I'll like to replace them all for aftermarket ones.
Thanks and LORD Bless!

On your 1st to 2nd problem. There is a Technical Bulletin out, which tells the Mazda mechanics to reprogram your computer. The problem is known as "Shift Shock". My son had it done on the 04, 3H/B and now it works like a charm.
Just go to the dealer and tell them that you're (meaning the car, HA!) experiencing the 1st to 2nd "Shift Shock" problem and they will reset the ECU.
