Went to fire up my 2010 JK on Saturday and instrument panel is inop. No speedo, no tach, no warning lights, no information lights, none of the turn indicator/light control arm and wiper control arm were working. A/C didn't work but the fan did. Strange thing is the wiper came on and stayed on until I turned the ignition off. Radio was working too.

On the way to drop it off at the dealership today I was playing around with the light switch and everything started working. Crazy. I tired to get it to fail again but no luck. I still dropped it off at the dealer to see if they can figure things out.

Anyone have any clues?

 

Ground check

 

Got my Jeep back from the dealership and the answer is.... Could not duplicate. I'm glad they didn't charge me anything for the diagnostic. Looks like I will have to wait and see if it happens again.

 

The JK has a fickle electrical system. Usually a resetting by disconnecting and reconnecting the battery will resolve such issues. If they persist, you'll need a new TIPM. However it sounds like you were just due for a resetting.
