Digital Insturment cluster


#1

Hi, I have a 89 Chevy Beretta and it has a digital instrument cluster in it,My speedometer skips around reading differnt miles per hour on it,what does that mean?..Do I need to replace the cluster or? also I can barley can see the panel lighted up is this a blub that is blown? its very dark.

The electrical connector for the cluster is probably a little loose-- it’s the same connector that gives it the Vehicle Speed Sensor data as well as the power to illuminate it. You’ll probably need to take it out and clean the connectors and make sure it goes back in snug.
