What exactly is your door issue? Describe in detail what is happening or not happening. Could be many things including a bad center roller or a bad fuel door switch. Hard to say without knowing your issue. (I have no idea what B2033 error code indicates.)
My problem is when I open the door it beeps three times but the door does not open automatically. Opening the door manually is no problem. Check the center roller or fuel door switch, no problem. I also tried unplugging the #7 fuse in the driver’s footwell fuse box for 15-20 seconds. The door just won‘t open automatically (sorry my English is no good)
Rubber bumpers, center roller, latch actuator, rear latch element, fuel door interlock, micro switch, all checked, beeps when push button is pressed to start, sliding door light on dash comes on, I've tried everything WiiMaster teaches. But sometimes I also try to unplug the No. 7 fuse in the driver's footwell fuse box for 15-20 seconds. The door would suddenly open automatically, but after a while, the sliding door light on the dashboard came on again. The error code checked is B2033. That's probably it.

Use a voltage meter to check all the micro switches. If I remember right they have BOTh kinds(normally open and normally closes) on the latch assembly.
Most likely one or more are not working correctly. They can be replaced individually, available on Digikey.
I'm glad to hear from you. Regarding the microswitch issue, I have tested and tried replacing the rear door lock actuator. Lubricated the front door actuator but the results were equally disappointing. After trying to remove the fuse, sometimes the door will open and close on its own three or four times. Then the beep sounded again and the door was stuck again. It's just that the control box hasn't been replaced yet. The picture below is the error code prompt I found on the Internet. But the motor was also replaced.

update status. There are two white rubber tubes at the center drum and motor outlet. Just hold the white rubber tube at the left motor outlet with your hand to open and close the door smoothly. Once you let go, the door will get stuck again. Does the center roller wire need to be replaced?
