Re: Win Module Failure
I had the same thing happen to my 1 day old Overland and I removed the negative battery lead to reboot the truck. It hasn't happened since but Jeep has released a TSB for this and I would suggest everyone get it applied.
TSB 08-024-11A, you can access it through the wk2jeeps link at the bottom of this page
