My wife's Acadia is having problems with the heating system. First, it was blowing cold air on the passenger side and the heat was working on drivers side. I actually bought a new blend door auxiliary, but realized that controlled which vents would be used, so I didn't put that new one in. Well, now she said that it's not blowing warm air at all and I believe she said that the control for the vents wasn't working. So, before I tear it apart and not even know what I'm looking for, I want to see if anyone has a idea of what could be causing this and what I should be checking?
