E300TD front electric window fault

[aston]

Reacurring f/passenger electric window (and electric d/mirror) failure.
If disconnecting battery and reset window operation all OK. However, if fault left for a day or so, driver's window fails. Can clear both faults by disconnecting battery. Tried changing passenger door module, but still getting window failure. Diagnosics show no fault on the modules? Can any help?

The mirror AND window stops working?

Whe it faults, disconnect the power to the motor and see if the mirror works again. That will help eliminate the motor.

You may have a broken wire too.
