avalanche 5,3 2003 problem Odometer

Hello,
I have an avalanche of 2003 5.3,
I have a problem on the odometer, it lights up when the contact is cut in my garage and when I roll there are lights that turn on and off from time to time,
Desol? for spelling I am in France

I can not post pictures

Take the bezel off and make sure your cluster is plugged in tightly, if that does not work, then I think you might have a loose solder joint on the pc board.  Good luck and welcome to the club and enjoy the wealth of information you will find here.

Thank you Didit,
I have dismounted the odometer but I can not open it because the needles do not come out,
Can the problem really come from there?
Contact cut, truck locked,
The odometer turns on alone,
Thank you for your help

Use a fork to pry the needles up.
