The wiring in my drivers door looked good, drivers window would not go up, wire was broken but insulation was not, found by pulling each wire, one pulled apart, spliced and window worked. My trunk would open with the key fob, but the latch would not reset to close in cold weather, thread had the grease in the latch mechanism holding it up, cleaned out the grease, only applied a little oil and it works all the time not. The unlock and lock mechanism is a motor and gears, seems unnecessarily complex, a solenoid pulling would seem simpler. My daughter's Beetle did the same thing. Since neither the remote or the door switch work, I'd look at the lock mechanism.
