Fuses for power windows
There are TWO fuses that you need to remove. We just sold our 190E so I'm going from memory.
In our car, one fuse controlled the L front window and the R rear window. Another fuse controlled the R front window and the L rear window.
I'm sorry but I don't know which ones they were. Pop the lid off of the fuse box and there should be a key that tells you which fuse is for what function. You should also be able to find the same info in your owners manual.
