I have a 2008 Saturn Outlook. I had serviced by GM tech. He fixed the AC but not the driver side vent will not change to heater. The shop went out of business the day after I got my car back. Been to the dealers they spend 5 hours to fix it. After 5 hours and 100 dollars it is still not fix. but it has been determined that the driver side door is jammed or the link is broken. Does anyone have a shop manual for the removal of the air box?
