WHAT GLUE WILL HOLD PLEXY GLASS ON A TRUCK WINDOW

is it a glue in one just clean of some of the glue but not all the glue make it as level as possible then go to a glass company and by window glue and 1/4 inch layer on the van and put new window in and put tap on to hold in place till dry

the glass in the door window is not normally glued in the regulator track but is pressed in the rubber with the use of soap which dries out and that means that the pressure of the metal is what holds the glass in place. There will be difficulties if the window guides are incorrectly adjusted and the glass is allowed to go up an angle instead of straight up.. Normally the track at the back of the door is fixed and the front track is adjustable to hold the glass correctly

Order some "Rhino" glue online. Raise the top about a foot and put a block of wood or a shoe box between the windshield and the front of the top to hold the top up in the air. Or use anything that will keep the top from lowering back down by itself. Now, go to the rear window and pull that flap piece that has separated from the glass up as far as it will go on the glass, Starting in the middle glue 3 inches at a time. Hold it down on the glass for 30 seconds or however long you feel comfortable. Then work 3 inches at a time to the left. When done with that do the right side. Let it sit 24 hours before removing the box or whatever was used to keep top propped up. That allows the glue to fully cure and it will last a long time. Remember, if you stretch it make sure you let it cure 24 hrs. If you just glue it where its laying without stretching it, you dont have to wait as long. If the inside has come undone, do that first, then wait 24 hrs and do the outside then.

u can"t glue on the mirror, instead, get the hole mirror it very easy to repair

You might consider thoroughly cleaning the area on both the glass and the piece you are trying to adhere to it, then getting "Rearview Mirror Adhesive", available in your local auto parts store for >$10.

Follow the directions on the product precisely, and the handle should stay on there for you.

First make sure the rubber seal has been cleaned totally out (broken glass chips ect.)Install the rubber seal. Then lighty glue a strong thin nylon rope in the rubber groove all the way around the groove the glass sets in. Leave a part of the rope out so you can pull on it. Then carefully set the bottom of the glass in the groove.Always hold a little pressure on the glass to hold it in.Then slowly pull the rope out. This will cause the rubber edge to come out and rap around the glass.

This problem is very common and is known as delamination.
Use Urethane adhesive to reglue the window.
This same adhesive is used to install windshields.
The hard part will be to hold the window in place till the Urethane cures.
Prepare for that in advance.

Presumably an electric window? Stand outside truck with door open and hold the window between your palms. Gently lift the glass to a closed position while someone activates the control (with engine running). You should be able to determine if the glass is jammed (moving glass slightly backward and forward should aid movement) or if a little hellp makes the window move easily.

If the window appears jammed, it could be off the track. A repair would require removal of the door panel.

If the window appears to only require help to close, your door motor could be getting weak or some how the window track could be causing a bind.

At least you should be able to get the window closed.

good luck.

I have the same problem. I got acetone and removed the old glue from the glass. Then  I reglued it with gorilla glue. This stuff explands into this yellow hard foam, so you have to be careful not to put on too much and not to get it on the outside of the top. I stuffed the back window area inside the car with pillows to push the glass up, then carefully applied the glue to the edge of the glass with a paintbrush. Then I covered the glued area on the outside with plastic bags of kitty litter to hold the fabric against the glass. Takes 4-5 hours to dry. Worked beautifully so far. Got a little thick and a couple places and I removed the excess with a razor blade. Then on the inside, I applied a small amount of the same glue with a paintbrush to the inside of the little track round the window. Then inserted the edge of the headliner into the track. Did all of this work with the top slightly opened to take the pressure off. So far so good. One week and counting. Hopefully it will hold up to the heat and sun. 

The rear window glass is glued in. This is best left to a glass professional, as the glue type & proceedure is very specific. Why? Because the rear glass, as well as the front glass, performs a secondary function to hold the roof panel somewhat solidly in the case of a roll-over. If the glass is not glued in properly, the event of an accident of this type may not compress the glass at the proper breakage point, which is bad. Best solution: Get a trained glass professional to do it for you.
Sorry to post this type of solution, but this is def a safety issue.
