Seat Ibiza 3 x electric windows failed

Check the fuses , especially fuses on left side of dash panel ,
# 50 Rear electric windows 30 amp . If not that you will have to pull door trims off and check for power to motors as a next step

Thanks for your help. Glasgow. Fuses all OK. There must be a single motor or relay that feeds the front offside and 2 x rear windows. It gradually deteriorated and now ceases to work at all from all selectors while the drivers front window is unnafected by the problem. Now trying to locate where the motor or relay is situated that might be the problem.

Thanks again
When activated individual electric window switches there's a click sound from the individual window operating system so the signal is reaching the motor. Occasionally there is some movement so I assume the fuse is not the issue. The fact that the 3 windows produced this result all at the same time while the drivers window worked and still does normally, led me to think there might possibly be an overall controller that is misbehaving, or water contamination in the wiring
Its where to start looking that I'm not good at and where to start looking for possible wiring problems. Appreciate your help

Pull a door trim , operate switch and test to see if power at motor .If so , and motor not operating , knackered motor .Repeat process on other doors Could also check windows are not jammed in any way and check window regulator mechanisms
