4,8is cluster is going crazy

[blabla30]

Hello together,

I have a problem with my cluster.

Suddenly when driving the gauges for water temp, fuel tank, speed and the rev counter are wriggling and then sometimes all four work again, but most of the time all went down to 0 and are not moving at all.

If I restart the engine there is a fifty:fifty chance that they work again. If not the gauges are wriggling again and then they are showing 0 again.

Does somebody had this problem already and could tell me what I have to do?

It´s a 4,8is with the specific cluster...
