E430 1999 loss of power in passenger door

4 days ago the window the power seat and door light at bottom of door were all dead. Today the same thing hapened to the driver door .does anyone know what it could be , is there a harness conection that conects everything or is there a relay that may have gone bad i would apreciate any help you may have for me . thanks

each door has a door control module witch controls all the functions for that door. it sounds like you have lost power the modules. the first thing you should check is the fuses. I am not sure where the fuse is, but thier is a fuse box under the hood on the pass side and thier is also one under the rear seat by the battery. if it is not the fuse then you will have to check for power at the control module.
