ECC Climate Control Temp Sensor Measurements Made Easier

I’m in the process of trying to figure out why the ECC climate control system on my ’97 855 GLT (158k miles) is unhappy and blinking its AC and REC lights at start up. As best I can tell the system functions as intended: AC is cool, fan blows normally, temperature tracking seems ok, position knobs for upper and lower vents direct the air properly, the recirculation switch makes the damper move into recirculate mode, etc. I’m just going through the system checking out components to try and find one or more that isn’t working right.
