I have a 94 xj and none of the lights on the left in the instrument panel turn on. I have had the jeep for about a year and they have never worked. A few months ago while out at pismo beach i hit a dip and the 4x4 part time light turned on which is the first time that any light has worked in that panel. It only stayed on for a few minutes and I haven't seen it since.. Any idea what could be causing this? Blown fuse?
