2013 Norge screen not working

Hi, I did a search but could not find anything. The electric screen on my Norge is not working. The previous owner did tell me it was temperamental. But I cannot get it to work at all. Is this a common fault and are there any obvious fixes please, apparently it was repaired last year and it was a relay !
Cheers

I would look at fuses first, then the switch, loose wires, corrosion in the terminal block. But if it was the relay before, it could be again, or a bad contact
