Drivers side back window doesn't work.

The relay operates all the windows. The drivers door switch is the master and has to be connected for the rest to work. It sounds like you have a bad motor or a bad connection on the motor in the drivers door.

Window regulator is bad in the drivers door . Do you know what a regulator is ? The Trainer 24 Power Window Troubleshooting Do you know anything about automotive electrical testing ? How to read an use a wiring diagram ? Do you know there are two side to a electrical circuit ? B+ voltage an a ground side . Plus there is electronic control modules and class 2 serial data network involved . When you push the switch for a window othen then drivers window on the drivers door . a class 2 message is sent to the other doors modules . The correct module will then open it's window .

I would check the fusible links at the starter motor to see if any fell rubbery which indicates they are burnt out.

take the inner door panel off, then jumper 12 volts to the motor connection, ( the one leading to the motor once disconnected ) to see if the motor even still works, if you hook the wires up backwards, no problem, Just reverse them to make it travel the other direction. if you find that the motor to the window works, back track to the switch, make sure its getting power with a meter or 12 volts test light, if it is,, push the switch to make sure its crossing through the switch supplying 12 volts to both sides, ( these switches are a normal pass through 12 volt switch, the only difference is the last 2 wires leading to the door side, flip flop, which makes the window go up or down) if you have voltage to and through the switch,, your window should work, ( assuming the motor checked out ok ) if wither of these 2 things doesn't check out good, replace them,, ( motor or switch) if you find that the switch isn't getting power, trace it back towards the drivers side switches,, and check the window switch lock, if thats shorted none of the other windows will work, and it would need to be replaced,

you have to run a power wire to the motor in the door and press up on the window button it should go back up if not then you need to change the button hook up or the motor

sounds like a window lift motor, maybe try and bang on the door a few times while you hit the button, if that doesnt work you may have to take the door panel off and test the wires at the window motor

It will be in the switch lift up the controls on both the drivers side and passenger side the wires going into the connection wiggle then and the button at the same time if you get any movement then you have a broken wire if not use a test light hook one wire to some metal and the other to the wires if their is any power the light will come on, if no light then you probably have a broken wire. The passenger side power comes from the drivers side control. When you open the doors you will see a large black set of wiring harness in the door going into the side under the dash that is the wiring harness for all the power windows and door locks, open it and test those wires for power.

it seems that the window motors are going out or bad

Sounds like your gears are striped out inside the motor. I had the same problem on a car of mine. I just went to a parts store and bought the gear and took the motor apart and fixed it myself. It cost 18 dollars with tax.

Good Luck.

Most likely the window motor brushes are sticking, but in any case the door panel must be removed to service the motor
