Bcm

Hi, I posted a week or so ago about our 98 concorde, I still have sometimes working sometimes not guages.. The car runs fine, has not stalled nor missed.. The 10 mph sensor for the auto door locks is also a little skrewey cause the guages aren't working,, also before they start we will hear a ding, then they will start working, sometimes for a few seconds, sometimes the rest of the trip, I was informewd it may be the Body control module,, if this were going bad what would the symptoms be,, Please I need your help I cannot take this to be put on a diagnostic, I have a 24 valve 3.5 in a 2.7 car and had to use the 2.7 com, the 3.5 com would not run the car.. It does not make sense but it has ran flawlessly for 30,000..I realy don't think the ecm is at fault, the car runs fine, please, any input would be greatly appreciated..
