Answer
Hi Enes,

If the cluster is faulty, take it back.  I think you got a different year, or even a different car all together.  Lumina and Cutlass are the same car, but different interior.  The parts will work, but may not look exactly alike.  Also, as long as the guages are reading correctly, I wouldn't worry.  Except to say, if the guages are annoying you, ask the saleperson about it.  I know many cars guages will hold their position until you restart the car.  Not a problem.  Possible the car the rebuilt cluster came from was this type.
