AC cold on passenger side, not drivers. Help!

I own a 1999 gtp. It has the dual climate control function and I noticed last summer that the driver's side will no longer blow cold air, only hot. The passenger side, on the other hand, blows cold air. Any help on what this might be? I was looking around online and I think it may be the heater blend door and/orthe heater blend door actuator, but I'm not entirely sure.

Thanks
 


You got it. Blend door or actuator is most likely the culprit. This isn't specific to dual climate system. The regular 3 knob systems can have these same syptoms as well, just an FYI.

I went to replace the actuator on mine and discovered it had already been done once before. Mine is still cold on the driverside, just not as cold as the pass side is. My problem is the door doesn't seal. I can stick my hand around the door and feel air coming out, so that's something to check as well.
 
Not to thread jack, but I am having the exact same issue, except opposite sides (hot passenger, cold driver). Where are these doors located??
