How do you remove the door panel on a 1999 vauxhall astra?

Answer

DOOR PANEL & TRIM REMOVAL.

1. Remove the 3 door panel screws, location as shown in the left photo above: Phillips head, located inside the pull-handle pocket tray. Torx screw, located behind the chrome door handle. This is also referred to as a "nutsert" and requires a Torx T-25 bit. The opening to access the screw is very small, screwdriver-style T-25 works best. Phillips head screw, located on the upper right top area (by the mirror bezel). It is covered by a round plastic trim plug that needs to be popped out (a small flat screwdriver works best for this).

2. Using a trim removal tool (Miller tool # C-4829 or similar), detach each of the 11 plastic trim panel fasteners. The easiest method I have found is to use a hard plastic putty knife to pry one of the bottom lower fasteners loose. You can reach behind the blade with your fingers to help pry it out. Once that is done you can reach underneath with your fingers and pull the door trim off by hand, slowly working around the edges to pop the rest of the fasteners loose as you go along. Do not let the panel fall, hold it somewhat in place until all of the wiring and rods are disconnected.

3. While carefully holding the loose trim panel out from the door a few inches, reach inside and remove both of the metal actuator rods. They are secured with yellow snap-on plastic retainer clips that need to be pried out and away from the sides of the metal rod. Lift the rods straight up and out of their sockets.

4. Unhook the large 15-pin white wiring connector by pressing in on the tab on the bottom side of the connector. Vehicles with the day/night mirrors will have an additional 2-pin white connector coming out of the main harness to unplug. Disconnect the 12-pin mirror connector from the short mirror harness. All wiring connectors have a tab on one side that needs to be pushed in to disengage them.
