A problem with the central lock: the car Passat B3

The problem with the central lock

I have such a problem with the central lock: the car Passat B3, then it closes, then there is no remote control. The motor buzzes, but the doors do not close. It happens for two days everything is fine, and then it does not close again. I don’t know what to do and what glitches I don’t know either. If I close all the doors manually and press the "open" button on the remote control, then nothing happens at all and the motor does not move, and when I press the "close" button, then all doors open, and the old one lasts longer, I press "close", motor buzzing but not closing, Help, what to do and how to be?

see microswitches in the driver's lock

Is it necessary to remove the driver's door trim? and watch there ?!

shoot on any and check the operation of microswitches
