Grang Voyager Power Windows

My '99 Grand Voyager's drivers side power window stopped working. I removed the master swiching unit/regulator checking the contacts as well as the motor. When I plugged it back in again - none of the other windows would operate.
Thinking I had tripped a fuse, I tried to find it but there was nothing labelled as such. Checking all the fuses showed they were ok.
Does anyone know where or what fuse is used for the windows. There didn't seem to be a thermo-fuse in the switching unit.....
