first of all – what do you mean that e-motor does not work? It is not releasing flap? you dont hear it?
it works very quite and it role is release the spring that makes bolt push the flap – that all. check that you still have there that spring – I don’t and thats why my flap is not recoiling
about cable – you just need to disassembly driver side of trunk and you will get access to cable and electric motor
