You seem to have more than one issue.  Why did the bar flex in the first place?  If you have a Craftsman or Liftmaster operator, unplug the operator and remove the cover.  On the motor shaft, carefully, use a pair of pliers or vicegrips to turn the motor shaft in a direction to move the carriage away from the bolt.  This may not be the only problem, the gear assembly part # 41C4220A may need to be replaced.  I'm still wondering why the bar flexed in the first place?

How to install the trunk lid torsion bars on a 2007 Saturn Ion?


The procedure is the same on every vehicle that uses this type of opening assist. So here is another persons instructions on a GM product.
Tools used:
Leather gloves!!
3/4" combo wrench (biggest I had)
1/2" deep socket (3/8")
6" extension (3/8")

1.With the trunk lid up and the curved part of the torsion bar against the rear trunk wall, I slipped the box end of the combo wrench around the torsion bar. I don't remember which way I had the angle of the box end facing. Just use what will work.

2.Then use the extension and the socket on the end of the torsion bar and push back so that you can get the combo wrench down past the curve, this is key. Once that is done you can remove the socket and extension. Pressure will push the wrench against the rear trunk wall.

3.Now comes the fun part. Push the wrench forward (VERY CAREFULLY) all the way past the side engine grill support and onto the peg of the hinge. The tip of my torsion bar just nicked the grill support. Make sure the wrench is seated well because it could slip around on you and cause your paint some damage and maybe even you.

4.Now that the torsion bar is on the hinge peg, you'll notice that your left with a wrench stuck on the bar... Just move (wiggle, twist) the wrench as far to the end of the torsion bar as it will go.

5.Take the extension, without the socket and place over the tip of the torsion bar. Push down while you slip the wrench past the peg. Remove the extension and slip off the wrench.

6.Now use the extension again to push down and put the roller (plastic, metal) bearing onto the peg.

7.Secure all the bolts, and lube it up.

That's it. Hope it'll help someone else. Please be careful.

2001 pontiac montana driver side window went down fine but will not come back up. is there anyway to get it back up if i need something new?


Thanks for using FixYa and welcome to the site. Since the window is not coming back up, it is either off track or the track bar is broke. In order to find out, you will need to take off the door panel. There should be a few screws on the side of the panel that needs to come out. There may be foam or plastic in the door that also needs to come out. You have a little bar that the window sits on. It raises the window. Make sure the bar is there and make sure the window is sitting on the bar. If the bar is broke, it will need replaced. If not, just sit the window on the bar and it should go back up. If you have any questions, feel free to ask and thanks for choosing FixYa.

I need help with my driver side window. I believe it's off the track. As press the button up and down I can see the track move but the glass is stuck. When open and close the door the I hear the glass...


Hi

this is very common, remove the door card or door trim and then you will see a plastic sheet careful how you take this off as if you rip it you will get cold legs while driving.

normally on the right hand side of the inside of the door you wil see a bar with either one or 2 10mm nuts or bolts these are to align the window in position you can normally tell if they have moved as the paint on the inside of the door will show where the nut or bolt should be like a coffee mug mark on a kitchen top.

simply put the bar back into the position to line it up again, also you may have to remove the window switch to get the door trim off put that to one side then reconnect it while the trim is off as you might have to move the window up and down to see the correct position and to take some of the presure off the galss, finally towards the front end of the car or the hinge part of the door you will see a runner for the window to sit into, ensure that the 2 edges of the galss are central to the runner / guide. you might like I say have to have the window up and down to get the right position bt you can always loosen or tighten the bolts / nuts to allow some movement.

hope I have not confused you thats the best I can explain it. get back to me if you need more help

Regards and have a great new year

Driver window off track,went to roll window down and window fell inside of door.Window crank turns freely.


remove door panel, If you are mechanically inclined you can figure out how to connect the regulator (operating assembly) back to the window by removing mounting bolts of assembly and pivoting. Something came loose or broke, window guides are worn (plastic parts), or assembly is way out of alignment for window to fall off track....

My drivers side window on my 1994 ford Taurus is stuck in the down position. how do i get it to go up and down again? the window motor is working ok. just that the window will not move


If the motor is working but the glass is not moving something must have broke inside the door. See if you can sneak a piece of duct tape down along side the glass, get it down as far as possible. Use a butter knife or something to make the tape stick to the glass, now try pulling the glass up with the tape. You may want run the window motor at the same time maybe it will catch. If you get the window up, tape it with duct tape so you can get it to a shop to get it fixed. Good luck.

My garage door will not stay down when I try to close it.


IF THE DOOR CLOSES ALL THE WAY WHEN HOLDING DOWN THE WALL BUTTON AND REVERSES 6" FROM THE FLOOR WHEN NOT HOLDING THE BUTTON.
I WOULD GUESS THAT THE SAFETY EYES ARE MOUNTED ON THE TRACK.
WHEN THE DOOR CLOSES THE TRACK AT THE BOTTOM IS TOO TIGHT CAUSING IT TO FLEX AS THE DOOR GETS NEAR THE BOTTOM. WHEN THE TRACK FLEXES THE EYES ARE POINTING FURTHER AWAY FROM THE DOOR AND EVENTUALLY THEY ARE TOO FAR OUT OF ALINMENT AND THE LED WILL GO OFF - THE DOOR GOES BACK UP.

SOLUTION: YOU CAN USE THE CLAW END OF A HAMMER TO TAP THE TRACK OUT A LITTLE WIDER - TAP NEXT TO THE WALL ON THE BRACKET THAT HOLDS THE TRACK TO THE WALL. MOVE THEM ABOUT 1/4" EACH SIDE.

OR

YOU CAN MOUNT THE BRACKETS TO THE WALL OR THE FLOOR.

THIS SHOULD SOLVE IT

HAVE A GREAT DAY

Window came off track nad wont roll up


you will have to remove the door panel and try to lift the window back up, have a look while holding the window up and see if the bolt/rivet holding the window onto the motor has just come loose or broke. Its quite possible its still bolted up to the assembly but the regulator has broken resulting in the window motor not being able to raise/lower window.
The regulators breaking are a common problem they have plastic usually that wears after so long.
