My C240's battery went dead last week. I put her on a charger, and she starts and run good.
However, I notice that my power window and sunroof is how having problems.
Sunroof - The sunroof will only move about an inch at a time for each time I press the button.
Window - the auto down operates well, but the auto-up function only works on the passerger front.

Can anyone give me Ideals where to look?
Thanks

Those systems need to be re-synchronized..should be a section in your owners manual.
