Hey so I installed a new pioneer head unit in and when I was installing it I blew radio fuse twice and since then all my gauges just stopped working but they light up any ideas on what happend I checked every fuse 5 times please someone help me
There's another fuse you blew somewhere. Check the ones under the dash by the driver door, I forget which # controls the dash circuitry, maybe you could find it in your Chilton/Haynes. One of the main power wires that power the entire gauge cluster is fused upstream somewhere.
The gauge cluster is right above the head unit. Maybe the connector to the gauge cluster came loose while you were installing the radio. I would remove the six screws for the instrument shroud and check the connector.
Circuit A1 from fuse 4 in the Power Distribution Center connects to circuit A21. Circuit A21 powers fuse 9 in the fuse block. Fuse 9 powers circuit G5. One branch of circuit G5 splices to power the gauges, speedometer, tachometer, voltmeter, indicator lamps, and warning lamps in the instrument cluster. Also check circuit Z1 since it provides ground for the instrument cluster illumination lamps, gauges and warning lamps.
Check pin 13 and 6. Those should be your ground. Make sure they are not loose in the connector. Do you have an electrical meter or anything that can test continuity? You should make sure that those wires are making it to ground.
If you do have a good ground check voltage for the volt meter with the ignition switch set to run or start. You should have around 12v between pin 12 and 13 on the connector. If you have 12v and the instrument cluster volt meter shows no reading then it is the meter that is shot.
