Question about 2004 Buick Rainier
Remove the negative batt cable again and try to reset system, this happens because the motors that control the temperature blend doors get out of syn with eachother, sometimes just removing the battery negative cable a few times fixes the issue, there is a new control head that fixes this problem but it is about $400
