Tried the battery cables but unfortunately that didn't work. I did go with that theory that there is possibly a grounding issue in the car. I traced the wires to each headlight/signal assembly and noticed that there is a ground wire that attaches to the frame. I took it off as it looked a bit rusty, cleaned it up, and low and behold, I was able to mess around with my message centre display. Reattached it and the car is fixed. Couldn't be happier as I do love this car. If anyone is having a message centre display problem, this is something definitely worth trying.
