2014 JKU. The AC Heater actuator died. So I replaced it. The rear defrost started blinking, looked it up, replaced the HVAC control unit. Still blinking. Went in an replaced the blend door actuator (passenger side), light still blinks. Got a OBD on it and it shows B11C3 and C4-00: front mode door 1 travel range too small and too large. And B1030-12 Evaporator Temperature Sensor-circuit short to battery.

So...after all I've done...what the hell is next and where do I find that damn sensor? I've looked all over the webz and I can't find anything about it.

Jeep Wrangler Air Conditioning Evaporator Temperature Sensor ...

repairpal.com › estimator › jeep Mounted on the evaporator core, this thermal sensor measures the temperature of the evaporator core constantly, and communicates the temperature back to the air conditioner control module. The control module will determine if the evaporator core is too cool, too warm, or just right. If too warm, the control module can adjust compressor output or expansion valve flow rates, which normally moves the evaporator core into the appropriate range.
