Have a 2010 Chrysler Sebring convertible that has an issue with the passenger window. When the top is up sometimes the window will start going up and down about an inch on it's own. Normally the window lowers about an inch when you open the door and when you close it will raise up an inch. It's ran the battery down in the past and lowering it all the way down doesn't seem to help as that will run the battery down also. I have a feeling that it's a sensor or door switch that's acting up, but don't know where to start or what to check. Looking for advice or suggestions before I go pay some dealer outrageous hourly rates to trouble shoot. Thanks in advance.
