electric window lifter rear go only from the front up and to

good evening together, my original electric window lifters at the back go only from the front up and to and the orange small lamps are also dead. who can help? the search and google didn’t help me any further. previous story: I took over the car with the defecated rear left window lifter, today the door boards were taken off and seen that the 4 pole plug from the engine was “only ́ ́ and put it back on again. since the heber goes up and to only from the front, behind there is nothing more, even the lighting of the switch is off. safety is i.o. many thanks for the help in advance mfg driversdt
