Just yesterday, the dash board quit working, turn signals don't work, head lights and tail lights are always on

More than likely you have an issue with a connector on the back of the cluster.

So, the easiest way to check this is to remove the cluster and check to make sure each connector is fully seated. What I would do is remove each connector and then reinstall them because you can't always feel a loose connector.

If each of the connectors are connected properly then we need to check the power coming into the cluster and make sure it is getting power.

I am attaching the connector views for the 3 connectors, and we need to check the power at each of the B+ connectors.

Please run through this info and let us know what questions you have. Thanks
