I was wondering if someone could let me know if they have had this problem as well and if anyone know what the issue is.
Sounds like your blend doors are out of whack . If you have the manual temperature controls , you can re-initialize them but since you specifically mention the driver/pass side , i assume you have the dual auto climate controls . That means a service call to jeep for diagnosis . I would try turning your climate control completely off, all the blend doors should close . Then disconnect the battery , push the break pedal for 5 sec and re-connect. That may force the system to reset itself .
Good luck .
