Trailblazer ext  
The digital display for mileage, trip-tic, and programming simply went dart while I was programming the door locks to activate when in gear rather than at slow speed. Nothing I have found will bring back the display. Other lighting components appear to be fine

It’s entirely possible that the BCM is failing, which wouldn’t be too surprising with a 19 year old vehicle. If your mechanic agrees that the BCM is the problem, remanufactured ones are not very expensive.

Is this the D.I.C. display?  
The rest of the instrument panel is working?
