The door post inside trim has gon limp like old lady's stocking's I know how to remove the post cover but dont know how to efect a good repair. For example can I restrech the existing material ?

more than like if its just on door that wont look and the hoon sounds the door actuator will be faulty and you will need to replace the actuator.
To do this you will need pull the inside door handle off.
remove all door trim covers to access screw and disconnect mirror wiring.
remove all screws around door trim.
very carefully remove door trim once the trim is off you see a plastic inner door liner don't rip gently remove half .
look inside door and you will see the door actuator and lock,carefull lift up locking tabs so you can remove all door rods from actuator.
on the outside of door undo the 3 bolts and actuator will come out.
get the new actuator and fit it the same way the old one come out.
Before refitting the trim grab some silicon and reseal plastic to door to keep water out..

remove screw on panal around handle that opens car. remove 2 screws underneath handle that pulls door closed. check around door panal edge for screws and if so remove them. Now remove panal by prying slightly around edges or panal as to pull the clips loose. Dont bother if some break,they can be easly replaced and dont cost much at all. I always use a still putty knife to help pry panal off. This insures you dont crack panal while pulling on it. Once thjis is dont you will have access to the switch...Simply replace it and place panal back on and HEY !! you did it..... hope this helps and if so Please leave rating on this post and good luck..

Your window regulator has failed. It is a fairly easy repair if you have some mechanical abilities. Simply remove interior door trim, there are mostly clips that hold this on but possibly a few screws/bolts. Under the trim is a water barrier that is attached with a tar looking adhesive, remove this as well but save it to re-install later. You'll have to pull the glass up inside the door to a point where you can get to the bolts on the clamps that hold it in the regulator, I like to use some duct tape to secure it in this position. DO NOT let it drop down inside the window again for this can break it. You are now ready to remove the old regulator.

Loosen the bolts that clamp the glass, find and remove the bolts that hold the regulator inside the door, disconnect the electrical connector to the motor.

Once you are able to turn the old part to the proper position it should come right out, Install motor on new regulator if necessary and install inside door, clamp window, connect electric connector. Now it's time to remove the duct tape and try it out, if all is good install vapor barrier and trim.

If this helps please leave me feedback.

the mirror cover is sold as a mirror in whole with all attaching parts. the inner door trim would be removed to get the old one off. start with the screws behind the inside door handle, remove wiring and all switches must be removed. next the trim can come off

Remove the door trim, Remove the plastic cover on the inside of the door where the mirror is. You should see screws retaining the mirror that undo from inside the car, and a small loom with a plug at about knee height behind the door trim. The rest is just replacing old with new and reassembly. Check under the electric window switch for hidden screws. Good Luck
