My driver side window is stuck in the down postion

You will have to remove the door panel

Most likely you have a broken window regulator
& are not going to get it up

If it is a switch problem,only,then you unplug the
motor & put battery voltage direct from the battery,
to get it up, until you have time to work on the problem

Take the door panel off and see if you can force the window up by hand. Or see if you can remove the motor itself then slide it up by hand the reinstall the motor until you get a new one.

Before you replace anything, inspect the connector pins in both the driver's door switch and the passenger door switch. If you don't find any problem with these connector pins, replace the driver's door control switch.

I HAD THE SAME PROBLEM DIAGNOSE MOTOR OR SWICH MOSTLY BAD SWICH ,BUY ON LINE EASY TO CHANGE

You may have a problem with your window's motor. This needs to be fixed at a shop. Hope this helps! Please give 4 thumbs up!

This problem is going to be a bad motor or window regulator, you will need to remove the door panel and check the regulator, the regulator is the most common but the motor can also be bad, if the window goes or sits straight and is not loose in its track then i would say its the motor, a quick trick is to hold the window switch in up or down postion and bang on the inside of the door hard and see if the window starts to work if it does then its the motor,

If you can't the the master switch at the driver door or the switch at its door to move the window then you need a new window motor. Chances are both switches are not bad.
Does the wiper move at all ? IF not then its either the switch or the motor. If it operates and just parks in the up position then its the parker switch.

Need to check power to switch - then to window motor -- to do this you have to remove drivers door panel and use and test light with the ignition switch in the on postion. With test light connected to window motor, press switch up or down , if light comes on and motor does not - replace motor - if no power at motor replace switch..

This is caused by the window express down module, if you quickly push the window switch down a few times does this correct the issue? If not have the express down module replaced.

BTW, the window seems to only get stuck down if it is taken all the way down - I've never gotten it stuck partway down. So in the summertime I try to remember not to take the driver's side window down completely, just keep it an inch or so up.
