Answer
Hi Larry, Sounds like you have eliminated the BCM maybe as being the culpret. The other things to unplug are the fuel data panel, climate control panel and the programmer for the hot/cold door. If unplugging the componant causes the other panel to light then replace that part. If not plug it back in and disconnect the next one. If unplugging all 3 doesn't get the panels to light then repost and I'll give you some other things to check. Hope that helps. Bill
