Ok, removing the front door panel is a bit hit 'n' miss the first time but once you found all the screw locations, it's a doddle.
1. Prise out the electric window control panel using a flat-head screw driver. Disconnect the two connector blocks.
2. Look down through the hole you've just exposed and you'll see the door release mechanism (wiggle the inside door release lever if you're not sure). You need to unhook the long silver rod/bar from the interior door release lever. It can be a bit awkward but should 'pop' out with a bit of force. Don't worry, it won't fall away, and is easy to pop back in when you refit the door.
3. Prise out the white interior light. Disconnect the connector block.
4. Now the screws! The locations are as follows:
- Under the little black cover in the handle/hole you use to close the door (that thing where you keep spare change and sweet wrappers).
- Down the panel edge nearest the door hinges (might be two here?)
- Two on the bottom panel edge
- Under the red reflector (prise this off gently with screwdriver)
5. Now lift the whole panel slightly and begin to pull away from the door. All the "pop" connectors will now cause you to have a heart attack as they release with a loud snap, but don't panic.
6. Once released, don't yank the panel too far as the (crap) speaker will still be connected. Disconnect the wire block connection for this and your done.
Fitting is the reverse of the above.
