e320 door module
I have similar problem:
driver seat; all forward,
no mirror driver side,
no window driver only,
no steering wheel adjust.
All relate to drivers side door.
I removed the door module,.ordered a replacement from ebay. The replacement was heavily corroded even w/ a pin missing. Returned for refund
Removed the OEM. It was corroded.. Cleaned pins and looked OK. Tested same not working.
Check 4 wire connector w/ key and off. NO power to door!
re-checked all fuses All looked OK
What (FUSE OR RELAY and where is it) controls the power to the drivers side door module?
Does a working module ASK for power and therefor NO power until asked???

UPdate: No power to door module.
Opened the door sill access to connector. Broken/corroded red power wire also two small brown were corroded/broken at the black door removal connector. repaired red wire .. Now power to four wire module connector at door module. Still not working switches at door panel. Did not repair two small brown wires (no clue what they connected to).
Purchased a tested door module.ebay $15.00. Installed. Still not working. Re-paired two brown wires which appear to be "signal wires talking to module. . now SEAT MOVED, MIRROR & STEERING WHEEL ADJUST. MEMORY WORKS IN 1,2,3 Door window does NOT work.
Then replaced new module with old module. All functions worked except window. SEAT ONLY WORKED FORWARD even in reverse position... explains why seat was all forward. USED MEMORY 1,2, OR THREE TO GET SEAT MOVING BACKWARD. ORIGINAL MODULE NOW PROVEN DEFECTIVE.
Reinstalled eBay module and seat works forward backward memory works and holds 1,2,& 3
Last item to repair door is window. Other windows work. Suspecting fuse or switch.
