all warning lights on, all gauges not working

[jane8888]

My 2000 Grand Cherokee Laredo is possessed. I'll drive along and then all warning lights come on, all gauges stop working (including the odometer), windows won't work. However, pretty much everything else does including head lights, turn signals, radio, heat, AC.

Everything will work normally after I disengage the battery, but it all happens again soon afterward. If I leave the battery disengaged all night, I can run all day without a problem.

What the heck is this??? I've checked fuses, too BTW. All okay there.

I'm checking this forum everyday in hopes of finding some help. Please, think guys !!

It may have a computer problem, or something that the dealer can find easly with their test equipment. I know most people dont like taking their jeeps back to a dealer due to the cost, but sometimes its the cheapest way to find the problem without replacing a lot of parts. Good luck
