Need technical repair help for outback loft lift system

I feel like I probably need to clarify my issue some more....the lift is getting power & it is functional, however only 3 of the 4 corners are lifting up the top.
One corner must have came disconnected or the cable broke/snapped & I need to figure out how to access the cables so it can be fixed.
I’m not sure if it’s in the ceiling over the toyhauler area or in the walls up in the loft.
Someone who’s owned one or worked on this model can hopefully offer some guidance.
