So I ran into a slight problem when trying to safety my 04 cavalier. The odometer light comes and goes as well so do half of the #s. Like the car has 279339 but half of the time you can only read 2_9_3_. I've tried changing the cluster with no luck. I've tried changing the plug that goes to the cluster with no luck. But now I have lost the back light for the odometer with the same cluster I started with. I'm scratching my head at this point. Does someone have any idea what would be causing this issue? If so any help or advice would be greatly appreciated. Please and thanks.
