The cluster is out of a 2002 Special and is in a 2002 ES Intrepid. The issue started the day after the install and has been intermittent. Every thing works on the cluster with the exception of the indiglo working when it wants to.

I'm surprised no one's replied to you yet. There are a few members on here that I'm SURE can help you and are familiar with 300m clusters and glitches. I am not. But personally what I would do if is take off check for loose connections and things of that nature.

The inverter and ballast for the EL sheet could be going south - I'm not sure where that is or how it is replaced on those clusters, but that''s my guess. You could possibly disable the OEM one and put in an aftermarket one from eBay or something - I'm not sure how much they'd be to replace, or what models could be used to replace it...

[tmknecht]

Me too.

I've done some research on EL, and it turns out that Ma has been using it since 1960 on the Imperials and it has expanded from there. I would like to hear from some one that has had success in repairing this kind of issue.

Yesterday I found out that heat seems to affect the operation. When the car is cold they dont illuminate, however on longer drives when the interior gets good and warm they will work. I am assuming at this point that it it a loose solder connection on the circuit board similar to the display issues on the atc heads.

Yep....take the cluster apart and try re-soldering the ballast connections.

It would be nice to have a pinout so I can bench test the illumination. Does anyone have access to alldata or would the fsm have the cluster pinout?

[Ronbo]

That info is in the FSM....look it up.
