Left mirror folding not working

[Ecmbuster]

Polish conversions are difficult ..... but
M21/1h1 = Mirror heater
M21/1m1 = Vertical Adjustment
M21/1m2 = Horizontal Adjustment
M21/1m3 = Folding Mirror Motor


M21/1m3 motor connections are Pin 14 and Pin 15 on the mirror. Apply battery power with N69/1 disconnected.
Reverse the polarity to move mirror IN and OUT. If the mirror moves, the motor works.

Test wire continuity from the mirror motor Pins 14 and 15 to N69/1 Pins 3 and 4
If the continuity is correct then test E6/5 for direction of Left Mirror
X30/7 will be the CAN messages and an oscilloscope is required to test the messages for CAN Hi and CAN Lo.
If the motors operates with a battery source and all the wiring connections are intact, it is very possible the door controller is defective for the mirror.

There have been instances when the mirror wiring or wiring connections are defective.
It is also possible, the mirror is incorrect and missing the folding motors. It is also possible the wiring harness is not correct (missing pins to mirror connector). Match the diagram to the connector and pins.
