I just bought a 95 grand Cherokee. With 4wd. The 4wd display panel is not w0rking. I've checked fuses all good to go. Any ideas? Locks into 4wd all the time and shifts to neutral and 4lo. Everything seems to work fine but the display is black. What could this be? Not sure if I just missed a fuse or what but would like to fix it. Hope to not have to replace panel completely.

 

Hopefully it won't come to having to replace it and not even sure if this is what you are talking about but......

Know nothing about ZJ's but for some strange reason remembered coming across it while stalking Ebay.

 

I will post a picture of the display panel I'm talking about. It is located under the heating controls.
