if you want every small detail call a jeep dealership, tell them the symptoms and they'll explain it. But they will probably try and use unnecessary language to confuse you. It is faulty wires in what I believe is the wiring harnesses that plug into the back of the gauge cluster and go to the ecu. Its not fun getting all that dash stuff off, but just pull where there arent any obvious screws and it'll pop out. I cleaned the plug recievers on the back of the cluster (there are two identical, rectangular white plug areas) and the two plugs from the wiring harness and just put it back in with as solid a connection as i could get. Its been two days now and its had zero problems so im keeping my fingers crossed. Like I said, give that a shot and if youre lucky it'll help. Otherwise the part is $8.20, $20 for parts from the dealer with things like heat tube and soldering wire, and around $100 for labor if you really want to bend over and have it repaired.
