My truck is doing something odd on the passenger hvac controls. I have it set to auto mode and passenger side gets hot then cold, then back to hot again and just repeats the process. I changed out the actuator in the middle of the dash to the left of the airbag but I am still having the same problem. I hooked a scanner up to it to see if I could see whats going on and theres a sensor labeled RH AC Duct Actual...I watch the sensor, once it gets below 70* it drops down and says in in the 20s and thats when all the heat comes from the passenger vents. Then after a little the temp resets and goes back to normal.

Where the hell is this sensor located so I can try changing that out? Ive been trying to track down some diagrams online but havent been able to find anything.

You changed the LH. RH under the passenger air bag and you need to pull the dash.

Inside the box? I thought all actuators were external of that box.

The one I replaced you can see from the glovebox, on top of the hvac box, in the middle of the dash and not in the lower section.
