Climate Control Problem

[GINO918]

Hey Guys

I'm brand new to the forum. I've been looking around for a solution to my problem. I have a 2003 G35 sedan. My problem is that my A/C will only work on minimum temp setting. As soon as I go up by one degree it switches over to heat. I have done some online reading and found that there is a interior temp senosor (thermistor). I have searched everywhere and can't find anything that would lead me to find where that is. Also when I hit auto it automatically sets the vents to the floor, even on the lowest setting...almost like the car thinks it's really cold or something. Am I even on the right path? Is this a common problem. My AC blasts Ice cold on minimum setting so I know mechanically everything is OK, it's just an electic problem. I also read these cars are known for bad control boards (whatever that is) which are expensive to fix. Any info is much appreciated. THanks

Welcome to NICO

Do a search for the FSM
Perhaps A call to the dealer service department could give you a clue if they have run into the problem before?

Good luck
