It sometimes goes down when I turn off the radio while driving. Sometimes it'll stay up after turning the radio off. Sometimes it will stay up for a minute or so after turning the radio off then go down. I haven't turned off the car with the radio on so don't know that yet. It always goes down when the car is turned off though. Its not a big deal but its not right.
As I said..its odd...like it has a mind of its own. Carriage House also changed out a faulty window switch...I bet they munged up the wiring somehow.
