I tried to search this problem, sorry if this is redundant. My tach, speedometer, and odo display is just blinking on and off roughly one second intervals. I pulled the entire display out looked inside, don't see anything obvious. Checked the connections look clean and good. No codes. . Reinstalled it. Now the same problem didn't go away. The fuel gauge has been very unreliable lately not sure if that's part of the problem. I suspecting a bad ground or something. But andy advice would be greatly appreciated. I'm kinda stuck now. Thanks for reading
