i disconnected my battery and reconnected it and now my windows will nut roll down/up automaticly you have to hold the button down till it goes down or up. it will not do th automaticly thing it used to do.
thanks in advance

 

Try taking the window all the way up, with the button half way pressed, as if you want to do it manually, until it's all the way up.
Then, hold the button all the way up as if you want auto close, and hold it there for 5 seconds or more.
Do the same at the bottom position reversing the direction.
That should reset the window to work automatically as I remeber having to do in my 2001 C240. Yours may be different.
I hope that works for you.

 

thank you so much tabourj by the way do you know how to reset the cd changer.
