My overhead console display on my 2000 Jeep XJ had never worked from the time I had bought the Jeep from the previous owner. The Jeep was in great stock condition and so was its electrical system. I checked all of my wires, connectors and fuses for my overhead display and they all seemed fine. I tried pressing and holding the overhead console display buttons in different combinations in hopes the display would turn on, beep, or do anything, but it gave me nothing. I thought maybe the display was burnt out because it had a burnt spot under the glass in the bottom right (see picture). However, my stock radio has this same spot and works just fine.
I figured I’d take my chances and buy a new display, however 2000 XJ overhead console displays are quite hard to find by themselves.



The solution lied in the connector on the top right of the board in the picture. This connector goes to the buttons that control the display.
I found that the connector can be plugged in upside down and right side up. However, when the connector is plugged in right side up it looks upside down.
When I flipped my connector and pressed the buttons, the display woke right up. The display had just been stuck in the off mode all that time. Because the connector for the button controls was flipped, the buttons weren’t able switch the display into another mode where the display is on.

The connector for the buttons has two little feet that stick out on one side. Those feet need to be facing away from the circuit board when the connector is plugged in.
This is deceiving because the connector looks like it is plugged in correctly with the feet pointing in towards the board.

This is what your connector should look like (Notice the two feet on the bottom left and right of the connector pointing out toward the camera):





Hope this saves you some trouble!
