Hardware Fan not working after replacement

[Schma0210]

Hi,
i changed a faulty fan on my daughters switch yesterday to a new one and now the fan isn't starting at all.
Tried with the old one as well and it doesn't start either. After looking for a solution i thought, that removing the diode behind the fan connector might be the help for this problem.
To my surprise there was no diode to take off. Has never been. Any tips, what i could do next

Does it get power?

1.020 volts after powerup.

Do the Joy-Cons charge when attached?

 

[Schma0210]

Yes they do.Or at least the charging icon is showing up. Haven't kept it on for a lot because of the fan not spinning. Don't want to overheat it.

Does it get power?

After checking again it gets power at the start. 4.99V and then drops to zero once the switch has started.
Fan does not spin.

Are the resistors still fine? They are near the connection in the board. (if the motherboard is facing towards you with the pointy side... so with the CPU away from you)

They seem to be okay. After connecting the fan once again the locking tab flew off, so i think it has been all the time the reason for the fan not to work. Sending the console away for a fan connector replacement.
