Pat_r32gtr

hey guys just wondering if anybody else has had this problem and would anyone know how to fix it. Ive recently purchased my gtr the problem iv got is that the climate control works but temp doesnt vary, it changes on the display but actual air blow out stays the same. Has anyone heard of this before and would they know how to fix???

Not sure if this helps, but parkmore smash repairs do an awesome job, im taking my car to him on tuesday $250 to spray the front bar and lip on a black 32 gtr.
