The signal light and hazard relay is the switch itself. There is no relay for the windows, they use a circuit breaker, 1 for the front windows and 1 for the rear. try the other windows, make sure that the child protection switch is off and if all the windows are inop, then begin your inspection with the master switch in the drivers door.
Hi, on your windows it sounds like the (drivers switch) master window switch, when the windows fail on that switch, try to use the switch on that the window is on. If it works then you need the master window switch. On your signal lights try checking all the bulbs and connections to the bulbs first. gl Ted
