Several times in the past couple days when startng my 98 TJ the Tachometer caution lite, Airbag lite and guages are not working. Seems like a loose connection since they generally do start working after a couple miles of driving. I had a Cherokee with the same problem a couple years ago, it turned out to be a loose wire plug at the back of the dash cluster.
Anyone had this problem on the TJ? Dale P.......... Sierra / Nevada
