How long does it take to replace window motor?

mabe the window is off track

You may have a faulty activation switch(your up/down),or youcould have a fried drive motor . the drive motor and windowcrank assembly are in side the door. I'm pretty handy and replaced my crank assembly with a used unit including motor,from a wrecker, in about 2 hours. alternative,find a good mech-anic.

The same thing happend with my 94 lesabre. I thought it was the switch but i realized that the switch was fine. I went at the junk yard and got my self a power window motor. That is proboably what is wrong with your windows. I recommend that you get yourself new or used window motors and that sould do it!

Best of luck

You need a window regulator.

Try "helping" the window the window to go down by pressing your hand agaist it and pushing it down . If it moves then the motor is not gone. My 02 Century driver window gets slow when it's cold or dirty. Try spraying some ArmorAll into the tracks on the door. This will not only help flush out dirt but lubricate as well

THE PROBLEM SOUNDS LIKE LOOSE WIRING CONECTIONS IN THE DRIVERS DOOR , BEST THING TO DO IS HAVE A LOOK OPEN UP DOOR PANEL AND CHECK ALL CONECTIONS, GOOD LUCK

All window motors work through the main four button switch, replace it with a donar .

Burnt out motor, or you've pushed a little button which locks the windows.

A couple of things to add to tinyp's solution. For Buicks, the regulator is bolted in, not riveted, which makes removal easier. Also, you'd better get used to this, as I have replaced 3 out of 4 window regulators on my 2002 LeSabre.

Could be a bad switch, bad window motor, or clutch in window motor, ccould also be that the window itself jumped track.
