I have run into a probelm with the Automatic Climate Control in my 2002 Santa Fe. Usually when it is 90F outside I tend to keep the temperature at 68 degrees. The way it rutinely works on the auto setting the air is cold with recirculate engaged and the fan speed on high until the cabin cools down. These last few hot days it doesn't work that way anymore. Now when i keep it at 68 degrees the fan speed is medium low and the recirculate is off and of course the air coming out of the vents is not sufficient enough to cool the cabin down. When I set the temperature all the way down to the lowest setting 62 degrees it gets cold again with recirculate engaged and the fan speed goes to maximum. I am suspecting it is a dirty or bad temperature sensor in the control unit but that is just a guess. For now I am keeping the temperature at 62 and running it on manual. When I push the AMB to get the outside temperature it appears to be accurate but I don't know if that is an indication that the outside temperature sensor is working at 100%. Does anyone have any suggestions on what I should check or replace?
