So this is very intresting, i parked my car in the airport for 7 days because i went into a trip, i came back only the passenger window was open! car was locked, how could something like this happen, lets say i forgot it open doesnt it close automaticaly after some time ?, there is no explination so far!.

Reset the "Force Limiter" settings for the windows. It's happened before and this always cures the problem. Read all about it in the manual   .............tony
