DevonDeville Posted August 4, 2011 Report Share Posted August 4, 2011 I recently bought a 1990 Deville and it started out with the Fuel Data Center and Climate Control ONLY displaying a lowercase 'd'. I researched and found that i needed to replace the BCM (Body Control Module) which I proceeded to do so. I got the car running and everything, but after i changed out the BCM, the FDC And CC ONLY displayed a lowercase 'c'. I have not been able to find anything that has been able to help me figure this out. Also, the a/c is CONSTANTLY on. not the whole a/c, just for the windshield. It turns on as soon as the car is on. I think it all has to do with some wiring, but i have NO clue. Any help would be greatly appreciated. Link to comment Share on other sites More sharing options...
CoupeDTS Posted August 5, 2011 Report Share Posted August 5, 2011 Fuses all good? I did a search before about instrument clusters and came up with some problems in those years. Maybe a fuse is out. Sounds like more than the instrument cluster though. Did you try a search? * 1966 Deville Convertible * 2007 Escalade ESV Black on Black * 1996 Fleetwood Brougham Black on Black V4P -Gone* 1983 Coupe Deville Street/Show Lowrider -Gone* 1970 Calais 4dr Hardtop GONE* 2000 Deville DTS - Silver with Black Leather and SE grille GONE* 1999 Seville STS - Pearl Red GONE Link to comment Share on other sites More sharing options...

And i've searched and searched to no avail. Link to comment Share on other sites More sharing options...
