My power windows not working. It had given me troubles in the past too, but it got working after a while by itself or at times I had changed fuse at the service station. Now, all four windows are not working and service says that I have to change the controller which will cost me 9.5K. Or change the relay which will cost me 450 only but rear right window will not work. Fortunately, my windows remained rolled up when this problem occurred. But driving on highway and opening doors in tool booths is a pain. Anyone has tried aftermarket controllers?
