Hello recently my power windows seats wipers horn and directionals stopped working in my 01 e320.Something tells me that its something to do with some kind of modular.Also what ever it is is draining my battery.Battery is good and so is the alternator had them tested.Sometimes the horn wipers and directionals work but never windows.Does anyone know what is causing this problem and how much it would be to be replaced thanks

You either have issues with the overhead control module and or the door control modules or more---regrettably they,the extended vehicle network, can not be tested with a cheap OBD scanner--that leaves you either live with the problem or have someone with factory or equal software scan the car to quickly find the faults!!!

below the rear seat is the location for many critical components. if water seeped
in and collected in that low spot, it has a way of wreaking havoc on many
functions. did you leave the roof open? plugged drain hoses? etc

Have you tested the simple stuff, fuses and connectors. though you talking about modular stuff and testing the alt and the battery makes me think you've already tested that but no harm in asking.
