  1. Hey all. I've been googling this issue for 2 days with no fix. I'm close to spending the money to get an rx330 service manual. My issue - Since last winter, the darn dual climate control will only put out heat on the driver's side vents on any warm temperature setting(above ambient), passenger side will only put out room temperature air. Cold A/C will come out of both sides just fine. AC diagnostics check says code 11, which I've read to be the temperature sensor circuit. I tested the sensor by the knee on the driver's side and resistance goes up and down with temperature, within ranges that I've seen for other thermistors--this one read 1.68 kohm last night. I checked the connector and read 3.5volts going to the sensor. Sprayed in contact cleaner and reconnected it. Still the same error. Are there two cabin temperature sensors in this car?? if so, where is the second one? It seems like there is a second sensor on the passenger side that thinks the cabin temp is high so it doesn't allow the air mix control to allow hot air through. My second theory is that the air mix control servos aren't working on the passenger side. I don't know what servo I was looking at but I could peek a servo moving up and down on the passenger side left knee area under the dash. it would move up and down as I changed temperatures. One last thing to note - i take it off dual climate control and the problem remains the same. My thinking is that the dual climate control off would mean it uses the one temperature sensor to control heat to both sides of the car.....
