Thing is that this problem started this summer and ever since has not gone away. I did not get the vehicle from dealership so i dnt know if it has warranty. I got it from an auto auction. I have owned the car for 2 yrs now. this problem just started recently. during the summer only hot air blows out. and during the winter only cold air comes out. I think its got something to do with the hot/cold knob.

I had the same issue with my RX-8, during my first year of ownership I ignorantly assumed I did not know how to correctly work it seeing that sometimes it worked and sometimes it did not. I eventually brought it to the dealer and was promptly charged $400 (including labor) to change the entire unit. Although it is not a recall issue this apparently occurs quite frequently. (As it was explained to me) when you turn the dial you should be able to feel little ridges that dictate the temperature setting however in the RX-8 the ridges wear down quite quickly leaving you without the ability to change the temperature on call. I unfortunately have not found a more economical solution as of yet. Good Luck

I will attempt to accurately answer your question, lacking the technical verbage my response might appear juvenile however the knowledge is sound. Due to the large amount of oil burned the rotary engine is considered dirty due to a lot of carbon build-up. The carbon build-up acts similar to cholesterol and an artery, revving the engine continuously provides and opportunity to prevent that carbon from building up (thats why manual is the best for this car). Owners of AT RX8 find themselves having engine problems with low mileage because the computer automatically shifts at low revs allowing build-up. I think I got all the info out
#113 of 131 10w 30 in my rx-8
Jan 07, 2010 (4:47 am)
I just bought a 2007 RX-8 AT with 53,000 miles. I was reading the discussions about what oil to use, so I checked the sticker from the last oil change (which I believe was just done by the used car dealer i purchased it from) and it says 10w 30 was used. I don't know much about the differences in oil so I was wondering if I should get it changed out now to avoid some problems or if it will be fine until my next oil change? I live in Jacksonville, FL Its freezing here now but we get pretty good heat in the summers, does anyone suggest putting in something other then the mazda recommended 5w 20 for these conditions? Thanks.

#115 of 131 underbody corrosion??
Feb 16, 2010 (10:30 pm)
My RX-8 just went in to the shop with a pretty good oil leak from a corroded oil cooling line. This is the second underbody corrosion issue in the last 6 months. I had the protective heat shield fall halfway off last August. I know I live in the north with road salt etc, but I am pretty faithful at keeping the car clean with a regular wash and underbody flush through the winters. Does anyone else know anything about a propensity for corrosion with a 2004??

yeah i just had to replace my oil cooler hose a little while ago. completely rotted out and leaking oil everywhere. mazda dealer wanted $400 to do it. so i bought the hose about $120 and replaced it myself. not a terrible job but takes some time. mazda knows about the problem and has issued a recall in Canada. No luck for us drivers in the states however. And as far as the heat and A/C not kicking in i recently just fixed this one as well. You need to remove the control unit with the knobs and resolder the connections at the circuit board, they just have a bad connection (on mine i could actually look through the holes, another issue Mazda knows about but does nothing to fix.
