Dash light will not come on and work. Already checked fuses and wiring.

If none of the dash lights work then it is unlikely to be a bulb. So we need to actually check power at the B4 terminal of the cluster and find out if you have power at the cluster when the lights are on.

Below is the wiring diagram that will help with this as well. Please let us know what you find with this because if you have no voltage then it may be a ground issue or a greater issue with the interior lighting system.

Also, we need to make sure we check the Steering column fuse. It is a 2 amp fuse that is in the base of the steering column.

Please let us know if you have questions on this. Thanks
