I don't know what version of a Crossfire y'all have, but I have had the entire dash cluster out several times. What provides the illumination is a standard 194 series wedge base bulb(s), as in incandescent. Takes about 15 seconds to change bulbs, you can get them at Wal-Mart.

As for getting to it, the official factory shop manual says you must remove steering wheel first, but IT IS WRONG. Just extend steering wheel out to furthest out and the cluster will clear enough to remove the two large keyed connectors that supply power and signal.

To get cluster out:

a) remove ingle screw and trim panel directly under steering wheel.

b) drop lower valence and knee pad section.

c) pull off the cluster surround trim (not so easy, the locking tabs are a royal pain) and four screws hold cluster to instrument binnacle.

MAKE SURE you tell the dealer tech he does NOT need to remove steering wheel, cause that would add much time and sweat.

I have replaced my dial face with cream colored 2004 SLK320 face, and all instrument lights with red LEDs, looks very cool but not cheap or rice rocket flash. Center console is also now blue LEDS, switches were a pain, but AC/Heater was easy (also 194 series wedge) base behind small plastic flap.

good luck...cjt
