I am clueless and a new owner of a used 2004 s430 - i hope i am posting in the right section? 5 times in the last 6 months my passenger side window and seat will not work and then a couple of days later they start to work again. Almost like i locked it and did not realize it? Except i have tried to unlock it and...I don't know?? Is this possible that its locked and I dont know how to unlock it?
