when it was wired incorrectly the climate control wouldn't turn on unless at max temp or min temp. Move it off that and you'd hear one of the doors in the HVAC slam shut. Once I verified I had it set up correctly I disconnected the battery, put the wires in the right spot and reconnected the battery, everything was fine.
I'm wondering, with all the different iterations I'd "confused" the climate system... so a reboot seemed to fix it.
This morning, temps in the 50's it ran just fine. Car seems to be running just fine, no codes.
