Hello all, this is a grand cherokee problem. My sister has a 1999 grand with 148000 miles on it. Couple of days ago she was driving to work and all the guages quit working andall the warning lights in the dash came on. The vech. still drove fine. Then everything was fine for a day and then it did it again. She has taken it to the dealer and they told her with the miles and age of the vech. that it could be anything and to trade it. She has know money so I am trying to help here out. Any ideas? Thanks.

Hey Moe,yes the speedometer has been acting up. Thanks for the offer on the wiring scmatics. I have got that covered.What was the tsb for resetting the gauges? Let me know and thank you for all your help. God Bless!!!!!

 

If you have a 4.0 engine also ck the ground wire on the passager side of the block. That also for the dash as well.

for the jeep the guages are all bussed info from the PCM. If the guages dont work and u still drive the pcm is good thus far so I would go with a cluster issue.
