Hi,
It sounds like you may have a wire that is broken and not making a good contact. Check the wiring between the door frame and the door itself. That is a common place for a problem.
Next, I attached the wiring schematic below so that you have a reference. Check the brown wire at the driver's side switch to see if there is a power supply issue. Also, confirm the black wire (ground) has continuity to ground, and the encoder power and ground wires are not damaged or loose at the connection.
Let me know.

See pics below. Note: The schematic was two pages long. I had to cut each pic in half to make them readable.
