Anyone have any ideas where to look to solve this?

Problem: on occassion, about every 5-6 days, the power windows, sunroof, both power seats, and rear shade ALL STOP WORKING AT ONCE. Sometimes it is just after I've driven the car and shut it down and then restarted it a few mintues later.

Any ideas on what the problem and how to solve it might be?

I'm a new Benz 'Fan' but the above is a real irritant.

Also, I do not have a factory manual as to how to operate certain features. As I recall once when I locked the car with the key the windows automatically closed except for about 2" gap on both rears. Obviously there is some sort of 'feature' on how you tun the key or hold it for a few seconds but I have not been able to duplicate that since. Anyone know what those 'features might be'?

Appreciate any tech help on this.

Regards,
