Greetings,

I ohmed out the outside temp sensor, but with the ohm meter I am using it measures in K so it's hard to tell if it worked accurately. Outside temp about 60 F and the ambient temp sensor out of the range showed about 200 ohms. The inside temp sensor when placed on a bag of ice caused normal heating operation in the vehicle, center vents closed, heat to floor and side vents. I would imagine the ice kept the sensor at 40 F or so. Measuring the sensor now in the house at house temp of 78 F the measurement is about 1600 ohms which falls within the operating range of the sensor. Could it be the temp wheel needs to be resynced as mentioned in the manual? Has anyone ever done this without the shaft locking tool, and if so how?
