I have a 99 saturn sl2 and juss my driver window wont go down or up.

SOURCE: 99 saturn sl2 has lost reverse

Last time this happened to me Saturn replaced valve body in tranny, this can be easily done at home if you are handy

SOURCE: vibration in motor

Check the gap setting on plugs. Also change the O2 sensor. This is usually the check engine light, or EGR-valve. You could also change it too. Then pull positive battery post off for a minute. THis should reset the computer.

It sounds like there is somthing wrong with the window regulatior ( the motor in the door that moves the window)
1.Remove the inner door pannel (all parts)
2. hook up the window controls & try moving window up or down, make sure window is moving propley in tracks and siscor arms are not bound up.
3.If all is well with the above stuff, just replace the window regulatior and test befor you reasembil the door pannel

if you are refering to a inertia switch like on a ford that kills the fuel pump in a crash, the saturn does not have one

Fore remove the door panel in a SL2, you have to take off the door handle. You have to disengage the door locking mechanism from the door handle, then unscrew the panel and take it off.

The door handle unhinges from the locks and from the window controls. If your windows are electric, just unsnap the cord attached and leave it hanging out.

You may have to work with the door handle as it won't come out of the slot very easily and you don't have a lot of room. A flat bladed screwdriver with a long metal piece should work to unsnap it.

1. Turn the ignition OFF, disconnect the harness connector at the driver window switch.
2. Test for infinite resistance between the signal terminals A and B and the B+ circuit terminal E with the passenger window switch in the INACTIVE position. If less than infinite resistance, replace the driver window switch.
3. Test for less than 2 ohms of resistance between the signal terminal A and the B+ circuit terminal E with the passenger window switch in the UP position. If greater than 2 ohms, replace the driver window switch.
4. Test for less than 2 ohms of resistance between the signal terminal B and the B+ circuit terminal E with the passenger window switch in the DOWN position. If greater than 2 ohms, replace the driver window switch.
5. Test for infinite resistance between the signal terminals F and H and the B+ circuit terminal E with the driver window switch in the INACTIVE position. If less than infinite resistance, replace the driver window switch.
6. Test for less than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal E with the driver window switch in the UP position. If greater than 2 ohms, replace the driver window switch
7. Test for less than 2 ohms of resistance between the signal terminal H and the B+ circuit terminal E with the driver window switch in the DOWN position. If greater than 2 ohms, replace the driver window switch.

1. Turn the ignition OFF, disconnect the harness connector at the passenger window switch. Test for infinite resistance between the signal terminals G and F and the B+ circuit terminal with the switch in the INACTIVE position. If less than infinite resistance, replace the switch.
2. Test for less than 2 ohms of resistance between the signal terminal G and the B+ circuit terminal with the switch in the UP position. If greater than 2 ohms, replace the switch.
3. Test for less than 2 ohms of resistance between the signal terminal F and the B+ circuit terminal with the switch in the DOWN position. If greater than 2 ohms, replace the switch.

1. Install a 30-amp fused jumper wire between the control terminal A and 12 volts. Momentarily install a jumper wire between the control terminal B and ground. The motor should perform the UP or DOWN function.
2. If the function does not perform as specified, replace the motor.
3. Reverse the jumper wires; the motor should perform the DOWN or UP function.
4. If the function does not perform as specified, replace the motor.

1. Raise the window to the full UP position.
2. Remove the upper trim panel.
3. Remove the manual window regulator handle, if equipped.
4. Remove the power door lock switch, if equipped.
5. Remove the pull cup assembly.
6. Remove the door trim push-in retainers.
7. Remove the screw from the trim panel.
8. Pull the bottom of the door trim out to disengage the clips.
9. Lift up on the door trim panel to disengage the inner belt molding from the door flange.
10. Remove the door trim panel.
11. Remove the radio speaker.
12. Remove the front door water deflector.
13. Disengage the door glass to the regulator sash channel clips. Separate the door glass from the sash channel.
14. Push the window to the up position and tape in place.
15. Loosen the power window regulator bolts.
16. Remove the rear regulator bolt.
17. Lift the window regulator, disengaging the loosened bolts from the door.
18. Disconnect the regulator electrical connector.
19. Remove the power window regulator from the door.

1. Installation is the reverse of removal.

1. Using a flat-bladed tool, pry the switch from the door trim panel enough to expose the locking tabs.
2. Press the locking tab to remove the switch from the door trim panel.
3. Disconnect the electrical connector.
4. Remove the switch.

1. Installation is the reverse of removal.
