My air conditioner is running cold on the drivers side but hot on the passenger side and back seat. I have found various threads relating to this and the fact that I probably need to replace the number 2 and number 3 actuators. But what I can't find is help to do this. I can find help with several makes and models but not the 2005 DTS. Does anyone know how to find the instructions for doing this? Where can I find a video? Where are the actuators for the 2005 DTS even located?
