Don't listen to that other guy.He has no idea what he's talking about.
As for your question,are you having problems with the window going down?If so,then there's a possibility it is the switch,but it could also be a burnt out motor.To test the switch,you're gonna have to remove the dash cluster panel.I'm not too familiar with where the switch is located on a Bronco,but I assume it's around this area.You're gonna have to remove the headlight knob to pull this piece off.You're gonna need an L-Shaped screwdriver or small piece of metal to get these off.There's a little spring in the knob that you will need to depress to take the knob off.All you need to do is stick the L-shaped screwdriver into the backside of the knob,and push towards you,while holding the knob so you don't turn the headlights on.After you get the knob off,there should be a couple screws holding the cluster panel on.Remove these,and any other components that might be holding the cluster panel on.After you've removed the cluster panel,you should have access to the switch.If you have room,test the voltage going to the switch.If you get nothing,then the switch might be bad.Check the fuses too,cause it might be that simple.If you get nothing for voltage,remove the switch and replace.If it still doesn't work,check voltage on the motor in the rear tailgate.
