Electric Seat Gremlin - help please

[Golffather]

All of a sudden I can't raise the seat!

It lowers fine but doesn't come back up again. Instinct tells me to lower more and try and raise it but too low and it's an issue with driving position.

The lumbar, backrest and forwards-backwards are working fine???

Any advice appreciated.

Number 20 is where the motor is.
Give it a knock, it may start working
