Loose rear window

[Steve73-2.0]

In searching out a noise from the upholstered panel covering the firewall in the cabin I discovered that the rear window is loose on its lower edge. I don't think this is the noise but it is a bigger worry. Does anything other than adhesive hold the window in? There are no clips visible and I am not sure something is missing.
Also what holds the middle of the padded back panel tight against the firewall? That's what I think is knockind when I hit a bump.
Any thoughts welcome.

Hello,
The rear window is held in with butyl tape (I think that is what it is called). It comes in a roll, is black and sticky and you simply roll it out onto the area where the window goes so it completely surrounds the window opening and then put the window in place and press it on all the way around. The factory also used a piece of black electrical tape to go across the bottom of the window. If you search on 914World.com and here too, you will likely see many threads about removing and resealing the rear window.

The rear back pad, if memory serves me, has screws that hold it in along the bottom and then you pull the bottom towards the dash and then pull down and the clips that secure the top of the pad to the firewall will come loose.

Good luck.

For the back pad: Remove the screws, pull the bottom of the pad forward, then slide the whole thing down. The hooks up near the top will let go and you can then pull the whole thing out. It's easier if you remove the seats, and you will need to remove the engine lid pull knob and the grommet around the pull cable. And remove the interior light, which means unhooking the battery ground because one of those wires is always hot!

Thanks for the advice. Old cars are like an archeological dig. The loose rear window was being held in by 2 business card pieces of tin (colour swatch cards) with one pop rivet and a plastic golf tee for packing!
The knocking sound seems to be that the backpad clips are not engaged.

If you don't fix the rear window, you'll rust out the car inside the cabin at the floor. Pull up some tar there and you might find some now, if it's been leaking during a rain storm.

When I did the repaint of my car I had a pro glue in the windshield and the rear window with urethane adhesive. I don't think I'll have to worry about leaks in my lifetime . Much better then butyl in my opinion.

If I remember correctly, there are 2 rubber strips (about an inch long and less than an eighth of an inch thick) that are placed along the bottom edge of the glass that support the weight of the glass when put in place.

Also the only purpose for using the black tape along the lower inside edge of the glass is so that you don't see the squished butyl tape against the glass from the inside of the cabin.
