Instrument Panel -- Lights Out F450

[redoil]

This may not be a diesel issue -- but my 2005 PSD 6.0 F450 Crew Cab has no lights on the instrument panel. I checked all fuses. Anybody know how to properly troubleshoot the switch?

I know this is a dumb question, but they aren't dimmed out are they? If not pull the switch out and check to see if you have power to the switch. Just pops out of the dash.

Here is a good pic to check the power to the light switch. 3-Gauge Install Pictures

No -- not dimmed out. I do have power to the dimmer switch as well as power to the headlight switch. The dimmer switch does turn on the interior cab lights when I turn it all the way up...but no instrument lights. I also took out the dash and took out the instrument cluster. all wire connectors are OK.

Hmm strange the fuses are good and everything else works. Check the wires on that pic for power make sure there is 12 volts to the instrument cluster.

WHere are those wires in the picture? Are they behind the instrument cluster? I assume that this would be after the dimmer switch so that it would be variable voltage?

[vitalidle]

Actually nope those wires in the pic are in the panel below the steering column.

I hate elec stuff. I had a penny fall behind my dash and it stopped my running lights tailights and intrument light from working

OK Vitalidle-- I'll check it out tomorrow. Thanks. I also have a 2000 Excursion 7.3 and want to put in a temp gauge for transmission plus extra cooler and exhaust brake. I tow a heavy trailer. I see from your profile that you have the Isspro gauge cluster. Happy with it?

[vitalidle]

Hope you get it figured out! Yes I am very happy with the ISSPRO gauges. I like the looks of the analog gauges on the piller. I think if you get guages and you go analog stick with ISSPRO or Autometer.
