[urq] Relay that controls the power windows?

... if both stopped at the same time it is likely to be the power or ground source that is the problem.  Each window has its own thermal fuse, and even at ~15 years it would be odd to hear both failing at the same time.  The thing that's nice about the urq is that you don't have all the complications of the newer cars ... and there's a lot less wiring going to the driver's door.  It isn't too tough to pull the console piece that has the switches ... first verify that you have power and ground at the switches, If so, connect up the switch for one side and measure power and ground while you activate the switch.  If you have no voltage when everything is disconnected or you see the +12 go down close to zero or the ground come up towards +12 follow the circuitry back toward the fuse box and battery.  If the voltage stays solid it could be the switches themselves (check the voltage going out to the window when the switch is on) ...
