2005 GC AC issue
 

I have a 2005 Grand Cherokee that is having a AC issue.
When set to full cold there is cold air coming out of the Drivers side Front Vents and warm air coming out of the Passenger Side ( my model DOES NOT have dual zone climate control ).
Has anybody else heard of this issue before.
When I do have it on full cold and just turn it a quarter turn it almost goes direct to hot air coming out of the vents.

even though you do not have the dual control, it may still have the devided door in the hvac unit. it sounds like the shaft has broken. There are numerous kits to solve the problem of broken flap doors available online that do not involve removing the whole dash to install them.
