Re: AC problem (I searched)
I had a similar problem. It turned out to be the fan speed switch. I replaced mine & now it's fine. I may have also repaired my old one, but I have not tested it. I got a complete control panel off of ebay.
2004, White Mazda 3s 5 Door, 3 sets of Kumho Ecsta ASX 225/45R17. Now on 3rd set of Yokahama YK520 225/45R17. 304,000 miles when totaled. 5th set of tires, 5th set of rear pads, New rear rotors, Original front pads . 1 exploded drive belt idler pulley, #3 motor mount, 4th gas cap, 2nd thermostat, flashed ROM & numerous trips to the dealer only to have them tell me that my A/C is fine! Than why doesn't it blow cold?
