Have to jiggle the temp. control knob to get either hot or cold. Sometimes when I finally get it on one or the other, it will switch to the opposite temp (ex: have it on hot and it will just switch to cold on its own). Cannot have any temp in between (so either HOT or COLD).

RookieThe heater controls in my car work off and on. I took it in for repair to the Mazda dealership and they were well aware of the issue. It is not recalled officailly, but was told that I could either pay myself or call customer service. (nightmare!) They would not cover it and it will be a $600 repair. This car is a lemon.

Hot air with air conditioning, cold air with heat. Wiggle knob and rotate to get correct temp. It sometimes takes a while to get the temp I am asking for.

A/C knob doesnt work. Only goes from 0 to 16 and nothing in between and you have to jiggle it and mess with it to get 16. This is clearly a common problem from the design of the car and should be recalled. Needless to say this and other problems with the vehicle (condensation in the taillights etc.) will make sure I never buy another Mazda. I love the car, but the service and poor design doesnt make it worth it.

Erratic temperature fluctuations. Wiggle knob or wires behind (up through the ashtray door). Have not repaired.

I had the same issue where jiggling the knob was the only way to change the temperature. The solution isn't really difficult. It'll take about an hour and a half. You have to remove the radio/climate control faceplate, then disconnect and remove the climate control unit. Disassemble it all the way down to the circuit board. There, the temp control knob will have 3 pins that go all the way through the board. If you look at the back side of the pins you'll notice: 1) There isn't much solder on it, 2) The solder is cracked. Just add more solder to the pins. I used Rosin based. Reassemble and test. Worked like a charm for me. Even if you've never done anything like this before, give it a try. You'd be surprised how easy it is.
