89 190E Windows won't open or close
 

Recently bought an 89 Mercedes 190E four door and having problems with the power windows. Drivers side front works well. The center console switch will lower the rear drivers side but will not raise it. You have to use the door switch on that door to raise it. The passenger side doors will not work at all. Tested the switches,( some were bad and had rattles inside) and ended up just replacing all the center console units. Passenger side still will not work. I have checked the fuses # 7&8, and they appear to be good. Haven't pulled the relay to check but don't think it's the problem since I am getting power to the drivers side. Any suggestions would help. I am to the point of just taking off the door panels and test jumping the respective motors to see if they are good. Thanks for any imput.
