Hi
I finally got round to making the adjustment.
I managed to get a selection of screwdrivers that allowed me to gain access to all the screws and I removed the whole blind to see how it works.
As rushallmanor mentioned above there is indeed 2 bushes at the top left side of each blind with a groove in each for a flat blade screw driver. It is best to open the flyscreen and the blind fully then turn each of the bushes clockwise to add tension.
The bush is on a ratchet therefore be careful to turn it clockwise then gently rotate anticlockwise to ensure the bush is engaged on the ratchet. Also when the screwdriver is in position do not push too much on the head of the bush otherwise it will be pushed away from the ratchet and will not lock and when you let go of the screwdrider the spring may well unwind if that is the case and the the spring will have to be fully tentioned from scratch.
I have tightened each blind on each window slightly as the springs have weakened slightly over the 3 years.
Within the mechanism of the faulty blind there was a length of white plastic cable (similar to the plastic on the reel of a strimmer) floating around within the mechanism of the blind. I have no idea where it came from and I have removed it completly, and the flyscreen and blind now work a treat.
The front centre blinds and the front right hand blinds have to be inched away from their fixed position on the left hand side to gain access to the bushes.
