tsteves5 Posted November 10, 2021 Report Share Posted November 10, 2021 So I've now replaced the rear HVAC mode actuator on my 2011 twice. The first time was about 7 months ago. I originally used an aftermarket actuator. Now the aftermarket has failed, so I replaced with an OEM Mopar version. I have a couple of comments to pass along if anyone else needs to do this in the future: Use an OEM actuator. It's such a pain to replace that you don't want to do the job twice. You do need to run the actuator calibration routine inside the vehicle's climate control system/computer. You do NOT need a dealership to do this. The calibration routine is available in AlphaODB. I use an OBDLink MX+ interface for connecting to the Journey. I bet that other Bluetooth interfaces will work as well. Consider running the calibration routine before everything is completely put back together so you know that it works before complete reassembly. 2late4u 1 Quote Link to comment Share on other sites More sharing options...
