Need to find out how to take out and repair the headliner

Here is how I fixed mine, not perfect but fairly successful

At the corners of the headliner you will see some trim moldings. They have to be remove make sure that if you see screws on the moldings that they get remove before prying them off. The trim moldings come off by prying them loosed. Pull on them, they should pot right off be careful not to break them. In the center of the headliner you will see some over head consoles they have to be removed to, check for hidden screws before trying to pull them off. Also disconnect the plugs on the overhead consoles.

and a GENERAL VIDEO on how to remove a Headliner.

You will need to remove the entire headliner, being careful not to crack the foam it is constructed. You will need to remove all the plastic door pillar covers, any clothes hangers, the dome light, etc.
You can purchase headliner fabric and adhesive at most fabric stores. The personnel there will assist you in getting the correct adhesive. You must remove all the old headliner fabric and backing pad material to get to the foam core for installation of the new headliner fabric. Lay out the fabric and cut it to size, allowing for some overlap in case you err slightly when positioning it. You will apply the adhesive to the foam core and to the back of the headliner fabric. It is a contact-type cement. Carefully position the fabric over the foam core and work from the center out to position it, being careful not to trap wrinkles or to stretch the fabric excessively. Trim off the excess and reinstall headliner.

3M makes an excellent spray glue for this. Clean off any loose foam first, spray both the cloth and the backing, let get tacky and stick together.

Hello,

When Your head liner starts to sag or You have another nice headliner You want to use in replacing Your old liner, it is actually a good thing. Removing and installing a new one is also a easy task and does not require any form of technicality to do this. Please get these instruments(Replacement headliner fabric, Spray glue adhesive, Screwdriver, Sandpaper, Scissors) and follow the steps below:

1. Remove everything that bolts into the headliner like visors, lights and coat hooks. These things are normally bolted to the ceiling through the headliner, making it impossible to remove the headliner with these things in place.
2. Take down the old headliner. You can grab it through the dome light hole or one of the other holes now showing. Be careful not to rip or bend the headliner. Slowly move it towards the rear of the car. You may have to remove some of the molding along the sides of the headliner.
3. Carefully take the headliner out through a door of the car. You may have to maneuver the headliner around the seats and steering wheel to get it out of a door. Be careful not to bend the headliner.
4. Peel the fabric off of the shell of the headliner. It should easily come off by pulling it with your hands. Use some sandpaper to remove any foam that remains on the headliner shell.
5. Lay the new fabric on the headliner in the correct position. Fold half of it back so the shell is visible.
6. Spray the adhesive glue on the visible side of the shell and on the underside of the fabric. Allow it to set until it has dried some.
7. Fold the fabric over slowly onto the shell. Smooth out any wrinkles as you go. Work your way to the outer corners of the shell.
8. Repeat the gluing procedure for the other half of the shell and fabric. Make sure to smooth out any wrinkles so the fabric doesn't completely dry this way.
9. Trim the left over fabric to 1/4 of an inch long. This will be hidden behind the molding of the car.
10. Install the headliner using the opposite steps you took to remove it. Slide it back into place, replace the molding and then the visors, lights and coat hooks

Hope this helped. Thank You for using FixYa!!!

You'll need to remove all the plastic trim around the headliner and the plastic clips holding the headliner up. There are a few places on the internet to get replacement headliner material.

No you do not have to drop the headliner!! Remove the glass and it comes out through the opening. Before you recover the sunshade you must sand the rubbery messy layer that the germans coat the piece with or you will never get the glue to hold for very long.

They do sell a headliner adhesive at your local parts stores. It can be a bit of a pain to do inside of the vehicle, but can be done. Just follow the directions on the spray can.
