Re: Dash lights stay on no gauges wj 4.7
Check first fuse 17 and 22 on the junction block under the steering wheel.
If ok, do a test of the instrument cluster. To do this, with the ignition switch in OFF, press the odometer button and while pressing it, switch the ignition in run. Now release the odometer button and the instrument cluster starts the self test, all indicators go full scale and return, all lights will be on and the odometer will count 1111111, 22222 etc. If this all is ok, at least the instrument cluster is ok. There could be a problem with a loose PCI data bus wire at the back of the cluster.
