i change the comfort relay.no difference
i changed the central lock module. no difference
i changed wiper module no difference.
i checked the wiring from door to windows motor. continuity is fine.
i even changed the ecu, no difference, i dont know what else left .

i can say windows motors are working i ve tried on other car.
by the way no curcit breaker button on the car. tomorrow i ll check the wiring from ecu to central locking module.

any ideas?

I do believe it's haunted.



You've got an intermittent/shorted circuit somewhere. It's going to be tough to find.
