190E clock and temp panel not working

clock and out side temp display is working on my 190E 2.3 1988 .
Any tips to find out the problem??

check fuses CAREFULLY. sometimes it hard to see that the fuse is split.

I've changed all the fuses. still no display

pull the cluster out and make sure everything is connected back there.
