Hey guys,
New here looking for some help diagnosing a problem before attempting to get a dealership to fix it under warranty... hoping I can get a little research done before hand.

Yesterday my sisters 2005 Mustang Convertible (4.0l V6/Auto) broke down at an CVS Drive-through... my sister put it in park, cut off the car, rolled down the window, and eventually had to get out of the car to reach the drive-through window to receive the medicines. when she returned to the car and started it the drivers window wouldn't roll up, the car would not come out of park, the transmission light came on, the oil light came on, and it said that the E-brake was pulled and it wasn't. after a few minutes of shutting it off and restarting it... it finally came out of park and the window went up and all the lights went off.

What in god's green earth happened? what could have been the cause? and how do I explain this to a dealership?

Also every time she puts the top back up the passenger window rolls up, back down, up and back down again before finally stopping the third time up. And in both her car and my 06 GT (5spd coupe) the airbag lights are on... I am unsure which code her's is putting out but mine (according the the blinks) is code 23. what does this code mean?

Any help with either problem would be greatly appreciated! thanks!
