Hello. My 2004 SS has been blowing hot air from the passenger side while the air is on. The drivers side blows very cold. While letting it run the passenger side never cools down. This is a duel temp system and of course both are set on cool.
Can anyone help troubleshoot?
TIA!!!

 

My 2005 was doing the same thing a few months ago except the drivers side was warm and the passenger side was cold. A friend suggested that I needed Freon. I figured if Freon was low both sides would blow hot air but he insisted and incredibly enough, put one can in and immediately it started working like a champ and still is months later, so I had to admit he was right.

 

More than likely it's the door actuator. Mine is doing the same thing except it's on the driver side. The one on the passenger side is very easy to get to and replace

 

Either a blend door or a leak and needing the system recharged. It's easy enough to go to a mechanic to properly vacuum test the system, I would never use a can.
