940 estate split-folding rear seats

[McGandalf]

Hi team,

I drove my 1992 Volvo 940 GLE estate to pick up some furniture I bought off eBay for the first time in a blue moon - only to find the split folding rear seats letting me down.

The seat back of the single, offside seat folds forwards happily. The seat back of the double, nearside seat (outer passenger and smaller middle seat) doesn't fold at all. The plastic lever doesn't release the catch by the C-pillar.

I managed to prise the plastic lever off, put a hook against the cable inside the seat, tug on this cable (pulling it away from the C-pillar) and release the catch by the C-pillar. However, the seat is still blocked from moving forward by something in the seat back towards the middle of the car.

Is there a further release catch by the middle seat - and if so, how can I release this using a hook/pliers?

I'll fold the seat forwards and then try to rebuild the catch release mechanism using the plastic lever.

Thanks!
