Drivers door multiple electrical issues in one go! 2009 Sov 2.7

[Darren J]

Hi all, hit a pole hole, parked up, locked car. Noticed driver door did not lock, but then found all below in one go don't work. Had everything apart to try and find loose connectors, broken earth's, chafed wires - to no avail. Been through wiring diagrams and tested black earth's under door card which seem OK and fuse f42 form power line 75 feed to driver door module which is OK. Any ideas? Driving me mad!

1. Neither mirror now power folds, although audibly hear click form relay in drivers door module (plus click off again 10 seconds or so later). Pivots on mirror seem fine and always in operation for 5 years before no issues. Have stripped drivers wing mirror to check and looks and feels fine. No attempt at motor movement by the way on button press, from either mirror.

2. Drivers mirror cannot adjust but passengers does.

3. Puddle and approach lamps on drivers not going on. Others on car fine. Door puddle lamp removed and checked on 12v. OK.

4. Drivers door does not lock or unlock on fob but fine on key (which also does unlock and lock other doors as well fine)

5. Dashboard light for drivers door open or closed works as it should so assume switch in latch OK.

6. Climate system does not start on automatically when starting car where it used to OK. OK when you turn on using touch screen or hit AUTO.

7. Windows all fine round car.

Help please before I have to admit defeat and go to the main stealers for diag.
