I had to replace the "mode" actuator because of a stripped gear. After I replaced it, air is blowing cold and then hot out of the vents. It also switches cold and hot from side to side. I did pull the wrong actuator at first. I pulled the one to the rear of the "mode" actuator, but I put it right back on. It seems to blow out of the correct ducts, but the temperature changes dramatically without changing the temperature setting. I read that to re-calibrate the HVAC system I should disconnect the battery and short the positive and negative battery terminals together, and then run the HVAC through all the modes and temperatures manually. I did that with no changes. I also read to pull the IP fuse for 60 seconds, but didn't try that yet because it was for a different year and model. I pulled the code and come up with a B0429, which from what I understand is the auxiliary temperature door. I am thinking that is for the rear. Am I wrong about that? Any help would be greatly appreciated. The wife is not happy about the constantly changing temperatures. Happy wife, happy home. Unhappy wife, unhappy home.I have seen some threads on here about similar issues, but it always talks about using a Tech2.
