Unfortunately you probably do need to replace the window motor , however as a preventative measure in the future use a special silicon lube you can aquire from Napa to lube up the window runners allowing less resistance for the electic motor to raise the wiindow in the future avoiding this problem.

SOURCE: installed new motor and regulator right door

Check the wires between the drivers door and body.Slide the rubber boot back far enough to look at the wires.They sometimes brake here from the door opening and closing all the time.If the wires are good you could have a bad drivers switch.Good luck.

SOURCE: power window on 1999 pontiac grand prix gt 2 door

what I would recommend is that you will have to test the window actuator first. You will need to remove the door panel to get at the actuator. From there, just jump the actuator to see if the window goes up or down. Don't worry about which terminal is positive or negative, they are switched back and forth by the control switches.

SOURCE: front window motor when out and window is down how

This sucks when it happens, I have 2 grand prix and have had this happened a few times, First, if you need to get it up RIGHT NOW! This instant even if its late at night? Well its do able. You can remove the paneling, dis engage the motor and prop it up. You might have to cut a piece of wood to hold it up temporarily so that someone wont break in and steal stuff. If you just need a fix it solution, there are a few possibilities, the first thing i would recommend would be to check the window switch, they tend to go bad often. You can do this by 2 ways, One? buy a new one, or 2 get a second grand prix switch from a friend or a neighbor or from someone else and plug it in. If this works, just replace the switch, if it doesnt, then remove the door paneling, and place electricity on one of the connectors on the motor (dont worry which side as they both receive electricity when going up or down) if this works, its a faulty switch, if it doesnt, it might be (95% sure) the motor itself.

re align the window track guides at the front and back of the glass . They are not parallel with the up motion and are allowing the glass to tilt and jam.

I have a 1999 pontiac grand prix. I put the window down today and it stopped halfway. I tried putting it back up but it would not move. I could hear the motor running both up and down but the window...


The cables on the window regulator broke or derailed, either way you need to replace the regulator to fix it. The regulator is the part that moves the window up and down.

I have a 1999 pontiac grand prix the window will not go up ? I have juice to the motor when i push the switch in the down position but nothing in the up. Do you think a switch or may be the motor?


I have a 99 grand prix, Its definitely the switch, I have fixed mine 4 times in 5 yrs (they are defective) I know because I have 2 grand prix and they both fail. Anyway, you can fix them if you know how, if you dont, see if you can borrow a friends grand prix switch to replace and try before you buy one (just a thought) and if you dont need your old switch, you can give it to me.lol. Hope this helped, It sucks not being able to roll your window down because of the fear that it wont come back up. Especially in the winter/Rainy Season...Let us know if this helped.

1999 Grand Prix gt window goes down but need to fiddle with switch (drivers side) to raise the window...nearly 10 to 15 minutes of jogging the switch... should i clean the switch or is there a bigger...


I own 2 grand prix, 99 with a 3.1 engine and a 99 with a 3.8 engine. Both of my cars
window switch have failed before, leaving me to a quick fix. I have managed to fix the switches on my cars (al thou they state they are not repairable, they are, if you can figure out what's causing it not work) They require a little more than cleaning, when you open it, you will notice some wire type things that balance back and forth (per window) you will need to first clean the inside and adjust the metal type things that rock back and forth, I dont have a set answer on how much, but it will be a trial and error. Or you can simply purchase one and that's it. Im almost 100% sure that it will fix your problem.

Pontiac Grand Prix Drivers side window won't go down


take the door panel off and see if your regulator is not stripped it is a cable regulator so the wire will be hanging if not try directly operating the motor at the motor and see if it moves up and down fairly easy and fast like new. if it does the problem is in the switch and will need to be replaced. the plug on the motor is a two wire plug and can be hooked up in either direction to make window go up and down.
