I have a 1999 Cherokee limited and the speedometer and all gauges in the cluster stop working and the airbag light goes on after going over bumps and taking hard right hand turns? Also the windshiled wiper motor was recently replaced although the intermitted does not work and wipers do not park. I found that if I go over a bump and the cluster goes dead I can get it to start working again buy squirting the windshield wipers or playing with wipers to get it to work again. Also the 4x4 green high light always stays on all the time even when the Jeep is not in 4x4 high. I looked at all of the forums and found some simular issues with the wipers and someone else that had an issue with their cluster but it affected their radio and that does not symptom . I check the ground and it seems to be okay. Pease help.
