The electric wiring for the windows and side mirrors will start making a clicking noise and when I put the key into the ignition and turn the key just one turn the front passenger window goes completely down and will not go back up until it is done clicking and turning the heated seats on and off. The regulator is not broke. Also the side mirrors even though they are programmed will sometimes just start moving and act like it cant move anymore and make a noise. The music and or radio will go out while its turned on, it will cut in and out and then after driving a while it wont cut in and out. For the window to just roll down it usually happens after it sat all night. Wont go back up for at least 2 minutes and you can see the door lights flicker and click.
