2004 saturn ion driver power windows switch will not work. Fuse good and passenger window switch works. The switch unit is good had a new on put on still did now work. Problems seems to be in wiring after the split off to the passenger window switch. No visiable signs of electrical fire the wires look good. What could be causing this problem?

After you disconnect the battery, you have to reset the security system. The immobilizer is stopping the car from starting.

Rear Passenger Power Window Operation
The rear passenger power window switches receive battery voltage through the window lockout control circuit if the window lockout function is disabled. Ground for the rear passenger power window motors is supplied through normally closed up and down contacts of both the rear passenger power window switches and the driver power window switch. When the either rear passenger power window switch is placed in the down position, the power window motor down control circuit is switched to 12 volts and is applied to the down side of the rear passenger power window motor. Since the other side of the rear passenger power motor is connected to ground through the normally closed up contacts of both the rear passenger and driver power window switches, the window travels down. By placing the rear passenger power window switch in the up position, the polarity of the power window motor is reversed and the window travels up.
The rear passenger power windows can also be controlled from the driver power window switch.

Did you try pushing the lock out switch on the drivers master switch ?

Hi there I am technical mechanical and electronic engineer mechanic you have a short in the circuit and you have to see wire diagram for it it may be some were else that is cause you the problem with it do a voltage drop test po-po and nev-nev

in drivers door

Did you ever solve this problem with your windows? My 03 Ion 2 is doing the same thing. We think it's a wiring issue. Any suggestions? Thanks, Kristen N!

no relay, its the motor. good luck.

it could be the switch,it could be the power window regulator,it could be the wiring in the door where the door meets the body,sometimes the wires in there break and cause this issue,,,go to the dealer to get parts,

is the window lock switch on?

If not you may have a loose plug on the bottom of the switch. there are two on the master switch.

You can also try hitting the inner door panel very hard (on the affected door) whilst pressing the window button down. Many times GM window regulator motors stick and seem defective. GM makes a killing on replacing units that are just fine.

dont know, but im having the same problem. my pass. side front wont work, and the driver rear wont work. its a 2005 ion 2 i suspect its the motors in both of them. i will let you know in a day or two, as soon as i check the parts yard to get a couple.

check the wires going from the driver door into the kick panel there should be a rubber thing around the wires and cut it off and the wires usualy break and loose connection
