chvydriver,
in your case a couple questions.
Do your rear tail lamps, front park lamps and license plate lamp work? Just check with the ignition off by turning the headlamp switch to Park position.
This park lamp signal is used as power feed for this INST LPs fuse and so if they aren't coming on your backlighting will not either.
You mention that your head lamps stay on also. Under what conditions: When your ignition turned on? When you are in any gear? And if your headlamps are on are your rear tail, front park and license plate lamps on as well?
If your rear tail.... etc lamps are working OK and the INST LPS fuse is OK then I guess I would be suspecting a wiring issue or the dimmer transistor ($20) in your vehicle when kaput.
The warning light you have on is probably the Service Vehicle Light, if it is the Service Engine that is a completely unrelated issue
