Hello, new here, my first post. My rear HVAC seems to be stuck in the a/c mode and won't switch over to heat. With winter approaching, it has become a top priority to fix it (according to my wife). I did have the annoying clicking noise coming from the RR interior panel, so I opened it up and replaced both blend air door actuators while I was in there. The clicking noise is gone, but I cannot get it to switch over to heat regardless of which control I use. I disconnected the battery and allowed the system to recalibrate after all my repairs. Any ideas to troubleshoot this issue would be appreciated.
