S Type JAguar Rear Door

drill it out or use a same size bolt and push it through

On both rear windows, or just one? If its just one then probably the regulator mechanism in the door has broken (there are some rather fragile plastic parts that can snap with age). The mechanism is easily replaced by removing the door trim (take out two screws found under the rubber mat in the door handle well, and pry off the whole door panel with a wide blade screwdriver or cats paw (start at top edge nearest to rear - 4-6 snap fittings should pop off reasonably easily). Unscrew old mechainsm and replace the whole thing.. Parts usually available on Ebay for $50 to $100, make sure you get the correct orientation, front and rear, and left and right, are all different parts - Lincon LS parts also fit perfectly).

If both windows not working and stopped at the same time... sounds electrical.. start checking fuses?

You should obtain a tool made specifically for removing door panels. They are attached by "snap" connectors, and by pulling on the door panel itself will invariably ruin it. Get the tool from a parts place and carefully peer into the slot between the door metal and the door panel. Use the tool slowly with resolution. You should really acquire a manual that guides you for your particular Jag.
Remember, to take the panel completely off, you need to remove the door handle. Look for a plug that has a screw under it. You'll need to pop the door window/lock control panel too, to access screws under there. This can be tricky, so be careful.

There are 2 or 3 screws under the panel and other one behind the handle (not the one to open the door, the one you grab to close the door) this one is covered by a round plastic tap, remove it first with a small sharp pointed tool, then very carefully try to pull out the entire panel, be very careful not to broke the clips, you also need to "unplug" the wire that opens and close the locks.

You'll need to remove screws that are by the door handle, arm rest, under door and side of door and then gently pull back on the panel as there will also be retaining clips attached and you don't want to break them. If needed, you can pull back the weather seal (can't reuse it, but it's not that important) and you will be able to access everything inside the door

the problem would be the wiring on the door, possible a break in the wire, therefore the window and the central locking isnt working, possibly the earth wire is broken, open the front passenger door and u should see a sleeve connecting to the rear door, that is where the wiring to the door is, check ! also i would check the fuses. thanks

Hi lec the rear glass has a white plastic clip holding the glass to the regulator. try from  the door side, pushing the center plastic pin out toward you then the glass will lift out   D

remove door panel adjust window so you can see the mounts the window is attched to remove screw's/ bolt's lower window lift up at angle and pull out slowly don't hit glass on edges will break .
