Spoiler used to work, now it doesn't

[TRCZ]

Hi guys, can anyone help me. When I first got my car the spoiler worked on the button, now it doesn't. The button doesn't light at all, and the spoiler isn't moving.
I check the maxi-fuses. Is it the green 30A one just to check? That seemed fine. I've replaced the switch, no change.

Anyone give me any tips? I'm really not sure how to take this forward.

Thanks in advance.
Trev.

ps I've had the cover off the boot lid and can make the spoiler rise and fall manually with an allen key, although it does feel quite tight.

Anyone help?
