Cleaned off snow started up, turned on heat, rear defrost , and wipers. Everything worked fine. I turned motor off after about 15 min. Returned about 10 min later drove away. Had no wipers ,no power windows, no heater no power in dash. Pulled over shut off motor restarted and now all is fine. Any ideas whats going on ? Thanks. 2008 3.3L 58,000mi.
