Hi John, sorry for the long wait on this question. This is a difficult problem to diagnose over the internet. Your window problem is caused by a fault in the CAN-B interior network. When a fault occurs in the network communication it can cause numerous items to stop functioning. Diagnosis it done with the Mercedes Star tester or by isolating the individual items on the network until the fault no longer occurs. The network cables all meet at the X30/7 connector in the passenger side door sill area. There will be a long connector with 8 or 9 brown and brown/red wires connected. You would disconnect one connector at a time until the windows started working. Once you have disconnected that connector that is causing the problem everything except the disconnected item on the network will function.
In regards ***** ***** hydraulic pump motor I usually locate used pumps on ebay or in the salvage yards. I have not found a suitable replacement motor. Top Hydraulics can rebuild your pump for $600. Copy and paste the link below.
