Hella VNT Turbo Actuator Help!

[rrr500]

Hello,
I have a Hella 6NW 008 091 turbo actator.

It's not working.
If i connect the actuator to a 12V power supply,it picks up a 0,05-0,06Amp from the 12V power supply.
So maybe it can work,but when i send the PWM signal for it,it does not work.

I tried to repair it but with no luck,because i don't know where i need to start?
Can somebody help me with a little information,to how do i repair it?
Here is a photo from and inside of the actuator: (I made the damage on the pcb's soldered connection lines)

Thank you!

Check motor carbons .
Most cases bad electro motor.

This is a harder problem than carbon brushes.
I'm not new in electronics.
I know more than basics.
If this was just a carbon brush problem only,i would not wrote silly questions here...
