91 Olds Trofeo problems

[91 Trofeoguy]

Hello:
I just bought me a 91 Olds Trefeo with original 82000 miles from my brother that had already fixed the problem of the Cluster shutting down, but the center console screen when the lights are on still has problems, it looks like there static and lines in screen, you can still see it and it runs great except once in a while there's a short or something and vehicle shuts down for a second then comes right back on, i mean split second, its crazy, I love the car and am so excited to work on it and keep it looking nice. Does anybody have any suggestions? Also looking for little grill running under the header panel on 91 olds trofeo, usually same color of vehicle, if you might know where one is??? thank you and thanks for the great website.....
